The Roulette taillight has 12 LEDs for brake- and taillight functions as well as 6 amber LEDs that can be used as left or right turn signal. When you want to use this function you will have to install two Roulettes, so they work great as a taillight conversion in hard saddlebags or other custom projects. Light is 3 3/16" (8 cm) diameter, is 1 3/8" (3.5 cm) high, features two M6 threaded mounting studs on a 4,3 cm center distance and comes pre-wired. Does not feature license plate illumination. The Roulette taillight is sold each.
