50 inch LED Light Bars

50 inch light bar guide

Fit, mounting and wiring for a 50 inch light bar

Everything buyers ask us before ordering a 50 inch bar, answered with the real measurements, the wiring diagram and the numbers from our spec sheets. The short version: measure the flat span, pick single row for a low profile or double row for maximum output, and everything you need to wire it is in the box.

Single, double or curved?

Single row: slim 2-9/16 in. tall housing for a low-profile windshield or roof mount. 250W and 33,000 raw lumens on 5W LEDs.

Double row: two rows of LEDs in a taller straight housing for the most output from one bar. 500W and 66,000 raw lumens.

Curved double row: the same 500W and 66,000 raw lumens in an arc that follows the roofline and spreads light toward the corners.

Will it fit?

Measure the flat span where the bar will sit, bracket to bracket. The 50 inch single row needs 53-3/8 in., the double row needs 52 in. and the curved double row needs 52-1/16 in. On full-size trucks, Jeeps and 4Runners that is the roof or windshield line; on boats, the T-top or hardtop. The vehicle kits below are pre-fit to their model years.

How it mounts

Every bar bolts down with the end brackets and hardware in the box. The bracket rotates so you can aim the beam after it is mounted. For tubes and rails, add a universal clamp bracket.

Roof or windshield lineThe classic 50 inch install. Curved kits for F-150, Silverado, Sierra, Tacoma, Tundra and 4Runner follow the roofline.
Jeep windshieldJK, JL and TJ kits mount a 50 inch single row or straight double row above the windshield. Bronco kits use a single row.
UTV roofThe Can-Am Defender kit mounts a 50 inch double row across the front of the roof.
Boat T-top or hardtopMarine bars in white housing, IP69K sealed for saltwater and washdown. The single row stays low at 2-9/16 in. tall so it clears the radar.

What's in the box

Nothing else to buy for a standard install. You will need a drill, a pencil and zip ties.

Wiring diagram

The harness is plug-and-play: connect the red lead to the battery positive, the black to the negative, run the switch into the cab and plug the bar into the Deutsch connector. The relay keeps the full load off your switch.

Light bar wiring diagram Battery positive runs through the inline 25A fuse to the relay. The in-cab on/off switch triggers the relay, and the relay powers the light bar through the 2-pin Deutsch connector. The relay and the light bar ground to the battery negative or a clean chassis ground. GROUND: battery negative or clean chassis ground BATTERY 12V or 24V +− 25A FUSE RELAY included ON/OFF SWITCH in cab, 3/4 in. hole trigger Deutsch 2-pin 50" LIGHT BAR Harness: 12 ft, fuse, relay and switch included Lead from bar: 16 in. to 2-pin Deutsch powergroundswitch trigger

Keep it watertightUse heat-shrink butt connectors or solder sleeves on any splice. The Deutsch connector can be cut off if you need a custom run.
Route it cleanZip-tie the harness away from heat, sharp edges and moving parts. Mount the switch where you can reach it seated.

Brightness & beam

Figures are for our 5W LED builds, the brightest version of each bar. Combo optics put a 15° spot down the center for distance and 45° flood on the sides for width; spot and flood-only versions are available on the single row, double row and curved bars. Double row and curved bars are 6,000K, and every bar is rated for 50,000 hours.

50 inch LED light bar questions

What is the brightest 50 inch light bar Black Oak makes?

The 50 inch double row and the 50 inch curved double row are the brightest, at 500W and 66,000 raw lumens on 5W LEDs. The 50 inch single row is 250W and 33,000 raw lumens.

Will a 50 inch light bar fit my vehicle?

Measure the flat span where the bar will sit, bracket to bracket. The 50 inch single row needs 53-3/8 in., the double row needs 52 in. and the curved double row needs 52-1/16 in. On full-size trucks, Jeeps and 4Runners that is the roof or windshield line; on boats, the T-top or hardtop. The vehicle kits below are pre-fit to their model years.

Single row or double row?

Single row when height is the constraint (behind a grille, on a roof rack, under a boat T-top) or when you want the slimmest look. Double row when the position has room and you want the most output from one bar, twice the raw lumens of the single row. Curved double row when the bar sits on a bumper or roofline and you want the beam to wrap the corners.

Does a 50 inch light bar come with a wiring harness and switch?

Yes. Every 50 inch bar ships with a 12 foot harness that includes the on/off switch, relay and inline fuse, plus stainless brackets and mounting hardware. It plugs into the bar's 2-pin Deutsch connector and runs on 12V and 24V systems.

What is the difference between the marine and standard 50 inch bars?

Same LEDs and optics. The marine bars use a white powder-coated housing and are sold with marine mounting options; every bar is IP69K sealed for saltwater and pressure washdown.

What warranty comes with a 50 inch light bar?

Every 50 inch Black Oak LED light bar in this collection is covered by a Lifetime Limited Warranty. See each product page for the terms.

Other sizes: 40 inch light bars, 60 inch light bars, or every size and type in LED light bars. Designed and engineered in Sarasota, Florida.
