Bontrager Flare RT Rear Bike Light

A compact and powerful rear light designed for maximum visibility in all riding conditions. The latest Flare RT is 36% smaller, 30% more powerful and runs 20% longer than the previous version, making it an essential daytime running light for road, path and city riding. Its focused optics, interruptive flash pattern and long‑range visibility ensure it can be seen from up to 2 km away during daylight hours. An updated USB port improves water resistance, and the integrated light sensor automatically adjusts brightness based on ambient conditions.
