Rock lights for trucks and Jeeps: pods, RGB, wiring and what is street legal
How to choose rock lights for a truck, Jeep or 4Runner: pod count, white vs RGB, waterproof ratings, wiring to a switch and the legal rules for driving on the road.
By OUTROOM Field Desk · Updated
Key takeaways
- Rock lights light the ground around your tires so you can pick a line at night, air down and work on the rig in camp.
- A 4-pod kit covers the wheel wells; 8 pods give full underbody and rocker coverage on a full-size truck.
- Look for IP67 or IP68 pods and sealed connectors; mud, pressure washers and river crossings kill cheap lights.
- Most US states restrict colored lights while driving on public roads. Use white, or keep RGB for trails and camp.
Rock lights are small, bright LED pods mounted under the body, inside the wheel wells or along the rock sliders. On the trail they show exactly where your tires are sitting. In camp they turn the rig into a work light for airing up, cooking and packing up after dark.
/ How many pods do you need?
| Kit | Coverage | Good for |
|---|---|---|
| 4 pods | One per wheel well | Jeep Wrangler, compact SUVs, side-by-sides |
| 6 pods | Wheel wells plus center underbody | Mid-size trucks: Tacoma, Ranger, Colorado |
| 8+ pods | Wheel wells, rockers and underbody | Full-size trucks, Bronco, 4Runner with sliders |
/ White or RGB?
White light gives the truest view of rocks, roots and ruts, and is the safest choice for anything you run near a road. RGB kits add color modes, music sync and app or remote control. They look great in camp and at shows, and most RGB kits also have a pure white mode for trail work.
/ Waterproofing and build quality
- IP67: survives temporary submersion. The minimum for anything mounted under a truck.
- IP68: rated for longer submersion. Worth it if you cross water or pressure wash often.
- Aluminum housings shed heat and survive rock strikes better than plastic.
- Sealed, keyed connectors stop water wicking into the harness.
/ Wiring rock lights the right way
- 01Plan the pod layoutMount pods where they face down and inward, away from the direct path of tires and rocks.
- 02Run the harness highFollow the frame rails, zip-tie every 12 inches and keep wires away from the exhaust and moving suspension.
- 03Fuse at the batteryUse an inline fuse close to the battery and a relay or the controller box included in the kit.
- 04Add a switchA dash switch or the kit remote makes sure the lights are off when you hit pavement.
/ Frequently asked
What are rock lights used for?+
They light the ground around your tires for night trail driving, spotting lines over rocks and working around the rig in camp.
Are rock lights legal?+
They are generally legal for off-road use. Many US states restrict colored lights while driving on public roads, so switch them off or use white when on pavement.
How many rock lights do I need for a truck?+
Six pods cover a mid-size truck well. Full-size trucks and rigs with rock sliders look and work best with eight or more.
Can I install rock lights myself?+
Yes. Most kits plug together with a controller box. Plan the layout, run the harness along the frame, fuse it at the battery and test before tidying the wires.
