They're performance rated, built with quality parts and backed by a lifetime warranty, so you buy them once.
RGB Rock Lights or Pure White Rock Lights?
- RGB rock lights run every color from your phone over Bluetooth — the go-to for show trucks and underglow.
- Pure white rock lights use dedicated white LEDs for the brightest, truest white light under your truck — ideal for trail work and wheel wells.
How Many Rock Lights Does a Truck Need?
4–8 lights cover the wheel wells on most trucks. 12–16 give you full underbody coverage, and 24–40 are for show builds and full-size trucks where every angle matters. Want a continuous glow down the sides? Add frame strips or an underglow strip kit.
Rock Lights vs. Wheel Lights
Rock lights light the ground, frame and wheel wells; wheel lights light the rims themselves. Many of our customers run both for the complete look.
Rock Light & Underglow FAQ
How are rock lights installed on a truck?
Every kit includes the harness with waterproof connectors, gaskets and mounting hardware. For a no-drill install, add magnet mounts (one per light).
Is underglow legal?
Laws vary by state, and some states (including California) restrict certain colors or visible underglow while driving. Use colors when parked or off-road and check your local regulations.
Are rock lights waterproof?
Yes — IP69 rated, built for mud, snow, pressure washing and water crossings.
