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 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.
