Paint the city day or night
The Flare R City tail light is daytime visible and designed for the city. A wide beam spread, focused optics, and an interruptive flash pattern make it visible from over 900m during the day. A built in ambient light sensor provides auto-brightness control, and the included Quick Connect bracket offers simple removal for recharging via the included USB cable.
35 Lumens of power and the wide visibility angle of the Flare R City tail light make you the biggest distraction on the city streets, day or night.
