Traxxas LED Rock Lights install directly into the inner fenders of compatible TRX-4^® and TRX-6^® trucks. Rock lights help illuminate obstacles underneath for trouble-free nighttime crawling. The kit includes two LED modules per wheel, ensuring a flood of light throughout the underside of the truck. Down lighting in the wheel wells combined with the headlight/taillight kit make it easy to see the orientation of the vehicle in the dark. Requires 8028 power supply and 8018, 8072, 8080, or 8080X inner fenders.
