30 Inch LED Light Bars

30 inch light bar guide

Fit, mounting and wiring for a 30 inch light bar

Everything buyers ask us before ordering a 30 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 tight spaces 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 grilles, roof racks and tight spots. 150W and 19,800 raw lumens on 5W LEDs.

Double row: two rows of LEDs in a taller straight housing for the most output from one bar. 300W and 39,600 raw lumens.

Curved double row: the same output in a subtle arc that follows a bumper and spreads light toward the corners.

30 inch LED light bar styles compared: single row, straight double row and curved double row
Illustration. Compare exact dimensions on each product page.

Will it fit?

Measure the flat span where the bar will sit, bracket to bracket. The 30 inch single row needs 33-5/16 in. and the double row needs 32 in. On most trucks that is between the tow hooks or across the lower bumper opening; on Jeeps, the hood cowl or upper grille; on UTVs, the front of the roof. 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.

Lower bumper / tow hooksThe most common truck install. Single row hides behind the bumper lip; double row for maximum output.
Grille or behind the grilleSingle row fits behind most grilles at 2-9/16 in. tall. F-150, 4Runner and Silverado kits use factory holes.
Roof rack or headache rackBolt to the crossbar with the included brackets. Great for UTVs and work trucks.
Boat T-top or hardtopMarine bars in white housing, IP69K sealed for saltwater and washdown. Aim forward for running, down for the deck.

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 15A 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 +− 15A FUSE RELAY included ON/OFF SWITCH in cab, 3/4 in. hole trigger Deutsch 2-pin 30" LIGHT BAR Harness: 12 ft, fuse, relay and switch included Lead from bar: 16 in. to 2-pin Deutsch powergroundswitch trigger
Factory upfitter switchesWiring into a Ford, Ram or GM upfitter switch? Skip our relay and connect directly; the upfitter circuit already has one.
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.

30 inch LED light bar questions

What is the brightest 30 inch light bar Black Oak makes?

The 30 inch double row and curved double row with 5W LEDs: 300W and 39,600 raw lumens. The 30 inch single row with 5W LEDs is 150W and 19,800 raw lumens, in a housing 2-9/16 inches tall with brackets.

Will a 30 inch light bar fit my truck?

Measure the flat span where the bar will sit. With its end brackets the single row is 33-5/16 inches wide and the double row is 32 inches wide, so that much clear space is needed between the tow hooks or across the bumper opening. Vehicle kits for Tacoma, Tundra, 4Runner, F-150, F-250, Silverado, Sierra and Jeep Wrangler JK and JL are pre-fit to their model years and use factory bolt locations.

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 and you want the beam to wrap the corners.

Does a 30 inch light bar come with a wiring harness and switch?

Yes. Every 30 inch bar ships with a 12 foot harness that includes the on/off switch, relay and inline fuse, plus the end 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 30 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 30 inch light bar?

Every 30 inch Black Oak LED light bar is covered by a Lifetime Limited Warranty. See each product page for the terms.

Other sizes: 20 inch light bars, 40 inch and 50 inch light bars, or every size and type in LED light bars. Designed and engineered in Sarasota, Florida.
