Rock lights are the fastest way to make a truck stand out at night, and the most common question we get is how many lights do I need? The answer depends on the size of your rig and what you want lit: just the wheel wells, the whole underbody, or every angle of a show build. Our RGB Rock Lights and Pure White Rock Lights both come in 4, 6, 8, 12, 16, 24, 32 and 40-light kits.
Quick sizing guide
| Kit | Layout | Built for |
|---|---|---|
| 4, 6 or 8 (small) | Wheel wells only, 1 to 2 lights per wheel well | Side-by-sides, smaller Jeeps, short wheelbases, or anyone just doing the wheel wells |
| 12 or 16 (midsize) | 3 per wheel well, or wheel wells plus a couple down the sides with even coverage | Midsize pickups, single cab short boxes |
| 24 (full-size) | 360°: 3 under the front bumper, 3 under the rear bumper, 3 per wheel well, 3 down each side | Crew cab short boxes |
| 32 (full-size) | The 24-light 360° layout plus extra lights for the added length in the center | Crew cab long beds |
| 40 (full-size) | Front, rear, wheel wells, sides, plus over the front axle, rear axle and driveline, with extras for the engine bay and accessories | The brightest build with zero shadows: the complete UFO look |
Small kits: 4, 6 and 8 lights
The small kits are built for side-by-sides, smaller Jeeps and short-wheelbase rigs, or for anyone who only wants the wheel wells lit. With a 4, 6 or 8-light kit you'll run one or two lights per wheel well. It's the clean, factory-plus look and a great first kit.
Midsize kits: 12 and 16 lights
The 12 and 16-light kits are made for midsize pickups and single cab short boxes. You can run three lights per wheel well, or light the wheel wells and put a couple down each side while keeping even coverage from front to back.
Full-size kits: 24, 32 and 40 lights
The full-size kits are designed for full 360° coverage. A typical 24-light layout puts three under the front bumper, three under the rear bumper, three in each wheel well and three down each side. That's the ideal kit for a crew cab short box.
Crew cab long beds usually need the 32-light kit to cover the extra length in the center without dark gaps.
The 40-light kit is for the guys who want the brightest setup with absolutely zero shadows. It covers the front, rear, wheel wells and sides, plus lights over the front axle, rear axle and driveline for the complete UFO look, and you'll still have extra lights for the engine bay and other accessories.
Plug-and-play and expandable
Every kit is completely plug-and-play. The lights plug into the harness and control box, with no splicing or soldering. Kits are also expandable, so you can start with the wheel wells and add more lights any time with single rock lights. Running a lift or a long wheelbase? Grab Rock Light Extensions for the longer wire runs.
Every light is a high-output light
Each 2-inch light runs three 16W Cree LEDs for 1,600 lumens in an IP69 waterproof, shockproof aluminum housing. Since every light is this bright, you get more coverage per light than with cheap strip-style pods.
