Sold Single: When the 4 / 6 / 8 Pack kits aren't quite the ticket, a single light comes in handy! This includes only one puck, no accessories, which are required for installation and operation.Brighter: Our proprietary second gen rock lights are designed to maximize intensity for well-lit trails and city streets alike. Each puck uses 12x 1W LEDs projecting through a high clarity polycarbonate lens, so no matter how you are using them, you can easily see and be seen. While theres nothing wrong with two, one puck will easily illuminate the entire wheel well with nothing but pure white light. Bash Proof: Backed with a lifetime limited warranty, the Morimoto Rock Light system is built to last. The beefy diecast housings have been powder-coated with the same finish as our Banger off road LED pods, and the 2mm thick lens is molded from Makrolon Polycarbonate, known for its strength in tough automotive applications.
