The kit uses existing wiring and housings. Each side uses four sections of two each for a total eight ultra-bright amber LED lamps to produce highly visible light, even in daylight. The installation features plug in and go simplicity and would be especially cool used in conjunction with their sequential tail lamp kit. There are no extra control boxes or wiring. Just install the lamps into your existing housings and connect to existing wiring. The kit is part number MP-HT-LED and the cost is $39.95. (800) 631-0507 www.mustangproject.com
