The sleek and aggressive Zot headlight and Dice taillight combo set delivers superior lighting for day and night use. Built with a road cyclists perspective in mind, both feature DayLightning mode to make riders stand out in broad daylight with powerful lightning-like flashes. Exclusive only to the Dice series, Cygolite’s adaptive flash technology switches from SteadyPulse to DayLightning depending on the time of day.
