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.
