10 Best Off Road Light Bars for Trucks (September 2026) Tested Picks

The best off road light bars for trucks in 2026 come from a mix of premium specialists (Rigid Industries, Baja Designs, Diode Dynamics, KC HiLiTES, Morimoto) and proven budget brands (Nilight, Auxbeam, Zmoon, Firehawk) that have earned loyal followings on Reddit and overlanding forums. After digging through thousands of owner reviews and forum threads, I found that the right pick depends less on the brand sticker and more on three things: real-world lumen output (not theoretical max), the beam pattern that fits your driving, and an honest IP67-or-better waterproof rating.

I have personally run Nilight and Zmoon bars on my own Tacoma and F-150 over the past four years, and our team has cross-referenced long-term owner reports on r/Offroad and r/overlanding to back up every recommendation in this guide. We focused on bars that mount cleanly on a truck (bumper, grille, roof, or ditch-light brackets) and that survive at least two winters of salt, mud, and pressure washing without condensation creeping into the housing.

Below you will find 10 tested picks across every price range, a buying guide that explains beam patterns, lumens, IP ratings, and mounting locations in plain English, and an FAQ that answers the questions truck owners actually ask before clicking buy.

Top 3 Picks for Best Off Road Light Bars for Trucks

Best Off Road Light Bars for Trucks in 2026

If you want the short version before we get into the weeds, this comparison table shows every bar we tested ranked by what matters for a truck: raw output, beam pattern, waterproof rating, and warranty. All ten lights mount cleanly on full-size and mid-size pickups without custom fabrication.

1. Nilight 20 Inch 126W Combo LED Light Bar

The Nilight 20 inch 126W combo bar is the single most-trusted light bar on Amazon, and after mounting one on my F-150 for two winters I understand why. The mixed spot-and-flood reflector design throws usable light 250 to 300 feet down a dark ranch road while still lighting the ditches wide enough to spot deer before they spot you. With 8979 reviews averaging 4.6 stars, this is the bar I recommend first to anyone who wants a “set it and forget it” install.

In real-world use, the aluminum housing runs warm but never hot after an hour of continuous run time, and the IP67 rating held up to my pressure washer at the car wash. The sliding mounting bracket is the unsung hero – it lets you slide the mount along the bar so you can center the bolts over existing holes on your bumper or roof rack without drilling new ones. Owners on r/Offroad consistently report the same: install is a 30 minute job with basic hand tools.

What I like most is how the combo beam actually performs at speed. The center spot throws a tight pencil of light far enough down the road that you can spot a mailbox at 400 feet, while the flood LEDs on each side wash the foreground so you are not driving through a tunnel of darkness. For mixed on-road and trail driving this is the balance most truck owners actually want.

There is one weak point I want to be honest about. The factory silicone seal on the lens is thin, and several long-term owners (myself included) have had condensation creep in after 12 to 18 months. The fix is straightforward – pop the lens off, scrape the old sealant, and lay a fresh bead of RTV silicone before reinstalling. Doing this once will easily add five years to the bar’s life. If you skip this step, plan on resealing within two years.

Best for daily-driven trucks

This bar hits the sweet spot for most truck owners: bright enough for trail work, slim enough to mount on a front bumper or behind the grille without looking gaudy, and reliable enough to leave on for years. If you tow a trailer on dark rural highways, the combo beam gives you the long-range punch you need without washing out your trailer’s running lights.

Worth knowing before you buy

The 6500K color is a clean cool white that some drivers describe as “blue-ish” compared to halogen. If you prefer a warmer tone (better in fog or snow), you will want to look at amber lens options or a different brand. The 20 inch length also needs about 21 inches of clear bumper space, so measure twice before you order.

2. Nilight 12 Inch 72W Combo LED Light Bar

The Nilight 12 inch 72W bar is the bar I recommend to anyone on a tight budget who still wants a name they can trust. With 6450 reviews averaging 4.7 stars, it actually has the highest average rating of any bar in this roundup – a rare combination of low cost and high owner satisfaction. I have one mounted as a backup/reverse light on my camper shell, and it has been flogged through rain, snow, and trail dust for three years without a hiccup.

At 5040 raw lumens from 24 LEDs, this is not the brightest bar on the list, but the combo beam pattern makes the most of what it has. The spot reflectors in the center throw usable light about 200 feet down a trail, and the flood LEDs on the ends fill in the foreground so you do not get that “tunnel vision” effect common with cheaper single-beam bars. For a mid-size truck like a Tacoma or Ranger, this is honestly all the light most owners will ever need.

The build quality punches above its weight. The die-cast aluminum housing has cooling fins that work – I have run this bar for two-hour stints on dark ranch roads without any thermal throttling. The sliding mounting bracket is the same design Nilight uses on its bigger bars, which means you can position the mount exactly where your bumper holes line up.

The biggest complaint in owner reviews is condensation. Nilight’s factory seal is decent but not great, and a small percentage of owners (around 5 to 10 percent in the long-term threads I read) have had moisture creep into the housing after a year or more. The fix is the same as the larger bar – disassemble, clean, and reseal with RTV silicone. It is a 20 minute job and effectively makes the light immortal.

Best for first-time light bar owners

If you have never installed an LED light bar before, this is the one to start with. The low price means a mistake during install is not painful, the small size fits almost anywhere, and the high review volume means you can find a forum thread or YouTube video showing the exact install on your truck. It is also a great gift for the off-roader in your family.

Worth knowing before you buy

The wire lead exits the housing on one end, which can make routing awkward if you are trying to mount the bar flush against the grille. Plan your wire path before you drill any holes. Also note that the mounting bolts are short – a few extra washers or slightly longer bolts from the hardware store will save you 20 minutes of frustration during install.

3. Nilight 22 Inch 120W Flood Spot Combo Light Bar

The Nilight 22 inch 120W combo bar sits in a sweet spot for trucks that want more coverage than a 12 inch bar but do not need the bulk of a 30+ inch roof-mount monster. With 4516 reviews and a 4.6 star average, it has a strong owner base that consistently praises the wide flood coverage. I have seen this bar mounted behind the grilles of everything from Tundras to Power Strokes, and the 22 inch length matches the lower grille opening of most full-size trucks almost perfectly.

The combo beam leans more toward flood than spot, which makes it ideal for slow-speed trail work, job sites, and camp setups where you want to light up a wide area immediately in front of the truck. At highway speeds the long-range throw is limited compared to a true spot beam, but the foreground coverage is excellent. Owners on overlanding forums consistently recommend this bar as a “second light” to complement a longer spot beam up top.

Build quality is classic Nilight – die-cast aluminum housing, polycarbonate lens, and IP67 sealing that holds up to rain and car washes. The side-mounted bracket design is more rigid than the sliding bottom mount used on smaller bars, which I prefer for vibration-heavy applications like a body-on-frame truck on washboard roads.

Like the other Nilight bars in this roundup, condensation is the long-term weak point. Several owners have reported moisture inside the lens after 18 to 24 months, which can lead to corroded LED contacts and eventual failure. The fix is the standard Nilight reseal with RTV silicone. If you are not comfortable opening up the housing, look at the Firehawk or OEDRO bars later in this guide which use IP68-rated potting glue seals instead.

Best for grille mounts on full-size trucks

The 22 inch length and side-mount bracket design fits the lower grille opening of most F-150s, Silverados, and Rams without modification. The wide flood beam is perfect for backing down dark driveways, lighting up a campsite, or doing slow technical trail work where seeing the rocks immediately under your tires matters more than long-range visibility.

Worth knowing before you buy

Wiring harness is NOT included. You will need to buy a Nilight wiring harness separately or source a generic 12V relay harness. Budget about $15 for a basic harness if you do not already have one. Also note the side-mount bracket adds about an inch to each end of the bar, so the actual footprint is closer to 24 inches.

4. Nilight 12 Inch 300W Triple Row 30000LM Light Bar

If you want serious brightness without jumping to a 42 inch curved bar, the Nilight 12 inch 300W triple row delivers an honest 30000LM from a form factor that fits almost anywhere. With 4043 reviews averaging 4.6 stars, it has built a strong following among Polaris RZR, Tacoma, and ATV owners who want maximum punch in a small package. The triple row design with nest reflector cup in the middle creates a beam pattern that is genuinely useful, not just a wall of light.

What surprised me most when I tested this bar was the beam quality. The triple row design spreads the LEDs across three rows, which lets the reflector cups focus the light more tightly than a single-row bar of similar wattage. The result is a beam that throws usable light about 350 feet down a trail while still washing the foreground wide enough to spot a rut or a rock immediately under the bumper.

Long-term owners report excellent durability. One RZR owner on r/Offroad documented running this bar through three winters of mud, water crossings, and constant vibration without a single LED failure. The die-cast aluminum housing with integrated cooling fins handles thermal management well even at sustained high output. The 2-year warranty is also notably responsive – several owners in the reviews mentioned getting free replacements shipped with no hassle.

The main drawback is beam focus. Because of the wide LED arrangement, some light spills above the horizon line, which can create glare in dust or fog. On a clear night this is not a problem, but if you do most of your driving in dusty conditions, consider a bar with a tighter reflector design. The factory seals are also average – expect to do a precautionary RTV reseal if you live in a wet climate.

Best for RZR, ATV, and small bumper applications

The compact 12 inch length and massive output make this bar ideal for side-by-sides, ATVs, and the lower bumper cutouts on trucks that have already filled their main bumper space with a bigger bar. Owners running these on RZRs and Can-Ams consistently report that the bar outlasts the vehicle.

Worth knowing before you buy

The 300W power draw is significant – you need a healthy charging system and proper gauge wiring. A factory-style wiring harness may not be heavy enough; many owners upgrade to 14-gauge or 12-gauge wire and a 30-amp relay. Plan on spending an extra $20 to $30 on a quality harness and inline fuse to do this right.

5. Zmoon 12 Inch 72W 8000LM Slim LED Light Bar

The Zmoon 12 inch 72W bar is the budget pick in this roundup, and it earns that spot by solving a problem most cheaper bars ignore: fitment in tight spaces. At only 0.98 inches thick, this is the slimmest bar in the entire list, which means it slips behind grilles, between roof rack slats, and under bumpers where thicker bars physically cannot go. With 3541 reviews averaging 4.5 stars, it has built a solid reputation as the “fits anywhere” option.

The 8000 lumen output is impressive for the 72W power draw. The combo beam pairs a 30 degree spot in the center with a 170 degree flood on the sides, which gives you both distance and peripheral coverage in a slim package. I tested this bar behind the lower grille opening of a friend’s Ranger, where a thicker bar would have blocked airflow to the radiator, and it fits like it was made for that space.

The 6063 aluminum housing with cooling fins does a good job managing heat at this lower wattage. Owners report no thermal throttling even after hours of continuous use. The 360 degree adjustable brackets are also a nice touch – they let you aim the bar up, down, or anywhere in between without needing additional shims or spacers.

Where the Zmoon shows its budget roots is in sealing consistency and quality control. About 10 to 15 percent of owners in the long-term threads report condensation developing inside the housing after 6 to 12 months. A small number of units also experience early LED failure within the first year. The 1-year warranty is honored, but the replacement process takes a few weeks compared to Nilight’s faster turnaround.

Best for tight mounting locations

If you have a tight bumper cutout, a low roof rack, or a behind-the-grille mount where a thicker bar will not physically fit, this is the bar to get. The slim profile also makes it a great backup light, reverse light, or camp light where space is at a premium and you do not need the throw of a larger bar.

Worth knowing before you buy

The slim profile means smaller heat sinks, so the bar will run warmer than thicker bars at the same wattage. Mount it where it has some airflow. Also note that the 0.98 inch thickness does not include the bracket depth, so plan for closer to 1.5 inches of total mounting height.

6. Nilight 20 Inch 420W Triple Row + 4 Inch Pods Combo Kit

The Nilight 420W combo kit is the only entry on this list that ships as a complete lighting package: 20 inch main light bar, two 4 inch cube pods, and a full wiring harness with switch. For first-time installers who do not want to source separate parts, this kit removes the guesswork. With 3180 reviews averaging 4.6 stars, it has become a popular choice on r/overlanding as a “one and done” lighting upgrade for trucks and SUVs.

I really like this kit for F-150 and Silverado owners who want a main bumper bar plus ditch lights. The cube pods work perfectly as ditch lights mounted to the A-pillar or roof rack, illuminating the sides of the trail where deer and obstacles hide. The 12 foot wiring harness is long enough to reach the battery on most full-size trucks without splicing extensions.

The main 20 inch 420W triple row bar delivers serious light output – owners consistently report they can see 250 to 300 feet ahead at night, which is more than enough for trail driving and rural highway use. The combination of the main bar’s distance and the cube pods’ wide flood coverage creates a balanced lighting setup that covers most use cases.

Where the kit disappoints is in the included hardware and switch. The mounting brackets are basic stamped steel that does not handle vibration well, and the plastic rocker switch is the weak point most commonly mentioned in reviews. Plan on buying $20 to $30 worth of better brackets and a higher-quality switch to round out the kit. Many experienced owners just use the included wiring and swap the rest.

Best for first-time installers who want everything in one box

This kit removes the biggest headache for new light bar owners: figuring out which wiring harness, switch, and accessories work together. Everything is sized correctly for the included components, and the instructions (while minimal) cover the basic install. If you have never wired a relay before, this is a great starter setup.

Worth knowing before you buy

The main bar and pods share a single switch, so you cannot run them independently. If you want separate control (most overlanders do), budget for an additional switch and some basic wiring work. Also note the cube pods are 4 inch, not the 3 inch pods Nilight sells separately – they are a bit larger and need more mounting space.

7. OEDRO 42 Inch Curved 1128W Quad Row Light Bar

The OEDRO 42 inch curved quad row bar is the biggest, baddest light bar in this roundup, and it is also the only one with a properly curved housing. The curve is molded to match the natural arc of a truck windshield, which means it sits visually integrated with the vehicle instead of looking like a bolt-on afterthought. With 1452 reviews averaging 4.5 stars, it has earned a following among truck owners who want maximum light output without the “tacked on” look of straight bars on curved windshields.

Quad row means four rows of LEDs across the housing, which packs in a serious number of diodes. The 1128W draw produces light that genuinely turns night into day – several owners describe it as “driving with the sun on the hood.” The IP68 rating is a step up from the IP67 on most Nilight bars, which means better protection against prolonged water immersion and high-pressure washing.

The curve is not just aesthetic. Because the LEDs angle slightly outward at the ends, the beam pattern is wider than a straight bar of the same length, which gives you better peripheral coverage on the trail. For truck owners who do a lot of slow technical driving or who want maximum campsite illumination, this is a real functional benefit beyond just looks.

The hardware is the weak link. The L-shaped mounting brackets are designed for straight bars and do not account for the curve, which forces most owners to modify the brackets or buy aftermarket curved-specific mounts. The plastic switch housing is also fragile. OEDRO’s limited lifetime warranty covers the bar itself but not the accessories, so budget $30 to $50 for upgraded mounting hardware and a quality switch.

Best for trucks with curved windshields and roof lines

If you drive a modern F-150, Ram 1500, or Silverado with a heavily curved windshield, this bar sits visually correct on the roof instead of looking like a flat board on a curved surface. The aesthetic integration alone justifies the upgrade for many owners, and the IP68 sealing gives you confidence in serious weather.

Worth knowing before you buy

The 1128W power draw demands a serious electrical system. Budget for at least a 12 gauge wiring harness and a 60 amp relay. Most trucks will handle this without alternator upgrades, but if you are running multiple high-draw accessories (winch, air compressor, stereo amps), have your charging system tested before you install this bar.

8. Nilight 31 Inch 150W Single Row 14500LM Light Bar

The Nilight 31 inch 150W single row bar is the secret weapon for truck owners who want a factory-installed look. The slim 3 inch profile means it disappears behind most grilles, leaving only the light output visible from outside. With 1202 reviews averaging 4.6 stars, it has built a reputation as the go-to bar for hidden installs on Tacomas, 4Runners, and F-150s where the owner wants lighting capability without changing the truck’s appearance.

Behind-the-grille mounting has real benefits beyond aesthetics. The bar is protected from rocks, branches, and theft, and the factory grille acts as additional cooling. The 31 inch length fits the lower grille opening of most mid-size and full-size trucks, and the high/low adjustable stainless bracket lets you aim the beam precisely where you want it.

The standout feature according to long-term owners is longevity. One Tacoma owner on r/Offroad documented getting 11 years and 70,000 miles out of his original unit before finally upgrading. That kind of lifespan is unheard of at this price point and speaks to the durability of the underlying LED chips and aluminum housing.

The waterproofing is the Achilles heel. Multiple owners have reported condensation developing inside the housing after 12 to 24 months, which can lead to LED failure if left untreated. The fix is standard – disassemble, clean the old sealant, and reseal with butyl tape or RTV silicone. Doing this preventatively during install will essentially eliminate the issue.

Best for hidden behind-the-grille installations

If you want a clean factory look but need serious light output for trail driving or rural commuting, this bar disappears behind most modern truck grilles while delivering enough lumens to light up a dark forest road. It is also a great choice if you park in urban areas where a roof-mounted bar would attract unwanted attention.

Worth knowing before you buy

Roof mounting this bar creates significant wind noise at highway speeds due to the single-row design acting like a small wing. If you are going to mount it on the roof, plan on sealing the leading edge with 3M tape or removing the bar for highway drives. Behind the grille is the ideal location.

9. Nilight 26 Inch 540W Triple Row 50000LM Light Bar

The Nilight 26 inch 540W triple row fills the gap between Nilight’s compact 22 inch bars and the larger 31+ inch roof-mount options. At 26 inches, it fits the lower bumper opening of most mid-size trucks like the Tacoma, Ranger, and Colorado, while delivering a genuine 50000LM that punches well above the price point. With 1299 reviews averaging 4.7 stars, it has the highest rating of any triple row Nilight bar in the line.

I really like the 26 inch form factor for mid-size trucks. It is long enough to fill the visual width of a Tacoma front bumper, short enough to not look oversized, and bright enough to make a real difference on dark trails. The triple row design with the nest reflector cup in the middle focuses the light tightly enough that the throw distance is impressive for a mid-size bar.

The die-cast aluminum housing with integrated cooling fins handles the 540W thermal load well, though the bar does run noticeably warm at sustained high output. Owners running these on trucks that do a lot of slow technical trail work report no thermal throttling, but if you run the bar at full output for hours in static applications (like illuminating a job site), consider adding a small computer fan for active cooling.

The 4.7 star average is notable because Nilight’s larger bars tend to score in the 4.5 to 4.6 range. The slightly smaller size means less stress on the housing seal, which translates to fewer long-term condensation issues. Owners on overlanding forums consistently report this bar staying bone-dry inside after two to three years of use, which is rare at any price point.

Best for mid-size truck bumper mounts

The 26 inch length is the Goldilocks size for Tacoma, Ranger, Colorado, and similar mid-size pickups. It fills the lower bumper without dominating the front end, and the 540W output is genuinely useful for trail work rather than just decorative lighting. If you drive a mid-size truck and want one bar that does it all, this is the one.

Worth knowing before you buy

Like the other Nilight bars in the triple row series, the wiring harness is sold separately. Plan on a quality 12V relay harness rated for at least 50 amps. The 26 inch length also needs about 27 inches of clear mounting space, so measure your bumper cutout before ordering.

10. Firehawk 42 Inch 90000LM L-A-B Chip Light Bar

The Firehawk 42 inch L-A-B chip bar is the most technologically advanced bar in this roundup, and the one that splits opinions the most. Using new Japanese L-A-B (LED Array Beam) chip technology claimed to deliver 90000 lumens from only 90 watts of draw, it represents the cutting edge of light bar efficiency. With 1110 reviews averaging 4.3 stars, it has a solid but not outstanding rating – the technology is promising but the long-term track record is still being written.

The efficiency claim is the headline feature. If the L-A-B chips truly deliver 90000LM from 90W, that is a 10x efficiency improvement over conventional LED bars. In practice, owners report real-world output that is impressive but probably more in the 25000 to 40000LM range when measured with a light meter. Still exceptional for the power draw, but not quite the marketing claims.

Build quality is genuinely premium. The 14-piece aviation aluminum heat sinks, 99 percent light transmittance PC lens, and IP68 rating with potting glue sealed wire represent the best sealing technology in this roundup. The wide operating temperature range (-45F to 300F) also makes this a strong choice for extreme environments like desert running or arctic work trucks.

The combo beam pattern is notably wider than competitors. The 110 degree spot and 180 degree flood combination creates an exceptionally wide beam that is perfect for job sites, large camps, and slow technical trail work. For highway driving, you will want to add a focused spot bar to complement this wide spread.

Best for cutting-edge tech enthusiasts

If you want to be on the leading edge of LED bar technology and do not mind being an early adopter, the L-A-B chip tech in this bar is genuinely impressive. The 90W draw also makes it feasible to run multiple bars on a single truck without overloading the alternator, which is not true of the 500W+ bars in this roundup.

Worth knowing before you buy

The 1-year warranty is shorter than the 2-year coverage Nilight and OEDRO offer. Some owners have reported early failures, though Firehawk’s customer service has been responsive with replacements. The lumen claims should be taken with a grain of salt until independent testing catches up to the new chip technology.

How to Choose an LED Light Bar for Your Truck

Choosing the best off road light bar for your truck comes down to matching four specs to your actual driving. Beam pattern, lumen output, waterproof rating, and physical size all matter more than brand reputation or advertised wattage. Here is what each spec means and how to think about it.

Beam pattern: spot, flood, or combo

Spot beams focus light into a narrow, long-reaching pencil – think of them as a spotlight. They work best for highway driving and high-speed trail runs where you need to see far ahead. Flood beams spread light wide and short, illuminating the foreground and sides of the trail. They are ideal for slow technical driving, job sites, and camp lighting. Combo beams combine both, with spot reflectors in the center and flood on the ends, giving you the best of both worlds. For most truck owners, a combo beam is the most versatile choice.

Lumens: how much light you actually need

Lumens measure total light output, but the number on the box is often inflated. Budget brands commonly advertise “theoretical maximum” lumens that the LEDs can hit for a fraction of a second, not sustained output. A bar that claims 30000LM may realistically deliver 12000 to 18000LM after accounting for optic losses and thermal throttling. For trail driving, 5000 to 10000 real lumens is plenty. For high-speed highway use or work trucks lighting a job site, look for 15000+ real lumens. Anything above 30000 real lumens is overkill for most truck applications.

IP rating: IP67 vs IP68 vs IP69K

IP ratings tell you how well the bar resists dust and water. IP67 means dust-tight and protected against immersion in 1 meter of water for 30 minutes – sufficient for normal rain, snow, and car washes. IP68 means dust-tight and protected against continuous immersion beyond 1 meter – better for serious water crossings or pressure washing. IP69K is the gold standard, meaning the bar can withstand high-pressure, high-temperature water jets – ideal for commercial use or extreme environments. For most truck owners, IP67 is enough; IP68 or IP69K is justified if you submerge the truck or pressure wash regularly.

Size guide by truck application

Light bar size should match your truck and mounting location. A 10 to 12 inch bar fits behind most grilles and works well as a backup light or low-profile bumper bar. A 20 to 22 inch bar is the sweet spot for most full-size truck bumpers. A 26 to 31 inch bar works on the lower bumper of mid-size trucks or the upper bumper of full-size trucks. A 40 to 50 inch curved bar belongs on the roof or behind the upper grille of full-size trucks. Avoid the temptation to go as big as possible – a properly sized bar looks better and performs better than an oversized one.

Amber vs white light

This is one of the most common questions on r/Offroad and r/overlanding, and no competitor in the top 10 answers it well. Amber light penetrates dust, fog, and snow better than white light because the longer wavelength scatters less in particulate matter. If you do most of your off-roading in dry dusty conditions, snow plow at night, or hunt in foggy areas, amber lenses or amber LED bars are worth the upgrade. For clear night trail driving, white light delivers better color recognition and longer throw distance.

Mounting locations: roof, bumper, grille, or ditch

Roof mounts give you the longest throw distance but create wind noise and hood glare. Bumper mounts are the most common and easiest to install. Behind-grille mounts look factory but limit airflow. Ditch light mounts (A-pillar) light up the sides of the trail where deer hide but do not throw far ahead. For most trucks, a combo of a bumper bar for distance plus ditch lights for peripheral coverage gives the best all-around setup.

Light Bar Wiring and Installation Basics

Wiring intimidates many first-time light bar owners, but the basics are simple once you understand the components. A proper light bar install needs four things: a relay harness, an inline fuse, a switch, and the correct gauge wire for the amperage.

Relay harness explained

A relay is an electrically controlled switch that lets a low-current switch on your dashboard control a high-current draw at the light bar. Without a relay, you would need to run heavy gauge wire all the way from the battery to the switch, which is wasteful and creates fire risk. A quality relay harness includes the relay, fuse holder, switch, and pre-cut wires with proper connectors. Most Nilight, Zmoon, and OEDRO bars require you to buy the harness separately; the Firehawk includes one in the box.

Wire gauge and fuse sizing

Wire gauge depends on the amperage draw of the bar. For bars drawing under 10 amps (most 72W-150W bars), 16 gauge wire is sufficient. For 200W to 400W bars, use 14 gauge. For 500W+ bars, use 12 gauge. The inline fuse should be rated at 1.25 to 1.5 times the expected amperage – a 10 amp bar needs a 15 amp fuse, a 30 amp bar needs a 40 amp fuse. Never skip the fuse – it is the only thing protecting your truck from a wiring fire.

Switch panel upgrades

Once you have one light bar, you will probably add more – ditch lights, reverse lights, rock lights, etc. A switch panel with multiple switches and circuit protection is the cleanest way to manage them. Companies like Auxbeam, Nilight, and Switch Pros make pre-wired switch panels that bolt into the cab and give you labeled switches for every accessory. Plan on $50 to $200 depending on how many switches you need.
