See me now

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.



Ride for longer with more battery life

Get a full 12 hours of runtime with all-day flash mode and feel secure in knowing there are 30 minutes of extra battery life built in for when you reach low power mode.



Wireless control

Connect with compatible ANT+ devices for always-on, battery status and wireless control
