Model 5298292

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 rear light make you the biggest distraction on the city streets, day or night.
