Rock Lights Overview Video
What Are Rock Lights?
LED rock lights are compact lights that mount underneath your vehicle to illuminate the ground below. Unlike light bars or headlights that throw a focused beam forward, rock lights cast a wide, unfocused flood of light for even coverage underneath the vehicle and around the wheels.
How Are Rock Lights Useful?
Rock Crawling Visibility: The original use case. Rock lights let the driver and spotter see exactly where the tires meet the terrain — critical for precision on technical obstacles at night.
Ambient and Work Lighting: Extra light around and under the vehicle is useful on the job site, loading gear in the dark, or anytime you need to see what's on the ground around your truck.
Campsite Lighting: Rock lights provide convenient ambient light for setting up camp after sundown — no need to hold a flashlight while pitching a tent or starting a fire.
Puddle Lights: Mounted near the doors, rock lights illuminate the ground at entry points so you can avoid stepping in mud, puddles, or anything else you don't want tracked inside.
Style and Accent Lighting: With colored lenses and RGBW options, rock lights double as accent lights. RGBW models offer strobes, fades, and music-sync modes for shows and events.
Where Can You Mount Rock Lights?
The compact size and multiple mounting options mean rock lights can go just about anywhere on your vehicle:
- Wheel Wells: The most common location. Mount at the 12 o'clock position for direct downward light, or at 10 and 2 for broader coverage.
- Truck Bed / Cargo Area: High output in a compact package — perfect for adding light without taking up cargo space.
- Under the Hood: Adds visibility for nighttime engine work without needing an extra hand for a flashlight.
- Roll Bars and Bull Bars: Use tube mounts to clamp rock lights to existing bars for top-down or forward-facing lighting.
- Roof Rack: Mount on a rack for overhead lighting in all directions — ideal for campsite setups.
- Interior / Dome: Add overhead interior lighting to trucks or UTVs that lack factory dome lights.
- Grille: Forward-facing grille mounts add extra off-road lighting from the front of the vehicle.
What Color Should You Choose?
Single Color Rock Lights are the way to go for maximum output and functional off-road use. They provide a more powerful, even spread of light. Interchangeable colored lenses are available in white, amber, red, blue, and green — snap on a different color anytime you want a new look.
RGBW Rock Lights give you full color control from a Bluetooth controller and app. Select any color, set up strobes, fades, and music-sync patterns. RGBW models trade some raw output for color versatility — best for style-focused builds and shows.
Mounting Options
- Bolt-On: Direct mounting with a single center bolt. The bolt hides inside the rock light for a clean look.
- Zip Tie: The fastest option. Built-in side tabs on Stage Series rock lights accept zip ties for quick attachment to any available point.
- Surface Mount: Mounts the light to any flat surface with a low profile. Includes a 20-degree angled rubber mount for directed lighting.
- Flush Mount: Installs the rock light flush into a bumper, truck bed, or panel for a fully integrated look.
- Tube Mount: Clamps onto roll bars, bull bars, roof racks, and cargo baskets. Fully adjustable positioning and direction.
- Magnetic Mount: No drilling required. A rubber-coated neodymium magnet holds the light securely — strong enough for rough trails with zero surface marring.
How Many Rock Lights Do You Need?
Most generic rock lights require two per wheel well (8 total) for adequate coverage. Stage Series Rock Lights are bright enough that a single light per wheel well handles the job — a 4-pack covers all four wheels. For full undercarriage illumination on serious off-road builds, an 8-pack with additional frame-mounted lights provides maximum coverage.
Are Rock Lights Street Legal?
Rock lights are not SAE-compliant and are not street legal. They're designed for off-road and auxiliary use. Check your local laws before operating rock lights on public roads.
Are Rock Lights Waterproof?
Stage Series Rock Lights carry an IP68 waterproof rating — submersible up to 1.5 meters (about 5 feet) for 30 minutes. They're built to handle stream crossings, mud, and whatever else the trail throws at them.
