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.
Bontrager daytime running lights are compact and powerful and feature an interruptive flash pattern that's daytime visible from up to 2km away.
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.
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.
When battery power dips below 5%, light output is scaled back to substantially extend the remaining battery life.
Not all lights are created equal. Bontrager Daytime Running Lights are designed to be visible whenever you ride, day or night.
