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.

Research shows that riding with a flashing, daylight-visible rear light is the single most effective measure a cyclist can take to increase their likelihood of standing out to drivers.

Daytime Running Lights

Bontrager daytime running lights are compact and powerful and feature an interruptive flash pattern that's daytime visible from up to 2km away.

240% more noticeable

When you use a flashing tail light during the day, studies show you’re up to 240% more noticeable than a rider using no lights at all.

Flash, focus, range

Not all lights are created equal. A true DRL is designed with specific focus, flash, and range to be seen from a meaningful distance during the day. Without these three things, you just have a light.

Longer Life

When battery power dips below 5%, light output is scaled back to substantially extend the remaining battery life.
