LED rock lights, also known as underbody lights, trail lights, or undercarriage lighting systems, are designed to illuminate the ground directly beneath trucks, SUVs, Jeeps, and off-road vehicles. Rock lights are a specialised type of automotive auxiliary lighting mounted to the vehicle frame, wheel wells, axles, or chassis rails, providing close-range illumination for terrain awareness during night off-roading, rock crawling, recovery operations, and campsite setup.
All rock lights in this category use solid-state LED technology, where light is produced by high-output semiconductor diodes rather than filaments or gas discharge systems. Compared with halogen auxiliary lights, LED modules provide higher durability, lower heat output, and longer operating lifespans, typically exceeding 25,000–50,000 hours under normal use.
Rock lights operate on the standard 12V DC automotive electrical system, integrating with vehicle batteries, auxiliary switch panels, relay harnesses, and lighting controllers. Because they are designed for close-range ground illumination rather than forward projection, rock lights produce a wide flood beam pattern with low-to-medium lumen output, ensuring that terrain near the tyres is clearly visible without creating glare or interfering with the driver’s forward vision.
The category currently includes two rock light systems, each designed around different functional requirements.
1. 9W Off-Road White LED Rock Light
The 9W Off-Road White LED Rock Light is a single-color surface-mount rock light module designed primarily for functional off-road illumination. It uses high-output white LEDs housed in a durable sealed light housing, delivering a wide flood beam pattern that illuminates the ground around tyres and suspension components.
- Typical locations: frame rails, wheel wells, suspension mounts, truck chassis
The light output is optimised for low-to-medium lumen ground illumination, ensuring clear visibility of rocks, ruts, and terrain obstacles without producing excessive forward glare.
2. Multicolor RGBW Rock Lights with Bluetooth Phone Control
Multi-color rock light configuration, combining RGB LEDs with a dedicated white channel (RGBW) to support both functional lighting and vehicle customization.
The system integrates multiple components:
- LED rock light modules containing RGBW diodes
- Bluetooth control module enabling smartphone operation
- wiring harness with fuse protection for electrical safety
- mounting hardware for chassis installation
This type of advanced rock light system is commonly used for off-road truck builds, Jeep trail rigs, and aftermarket lighting customization projects.
All products in this category use solid-state LED technology, where light is generated by high-output LED diodes inside sealed light modules. Unlike traditional halogen auxiliary lights, LED rock lights produce lower heat, higher efficiency, and longer operational lifespan, making them suitable for harsh environments such as mud, water crossings, and rocky terrain.
