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



240% more noticeable
When you use a flashing rear 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.
