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
Research suggests that riding with a daytime-visible flashing light is the single best product solution for making a cyclist more noticeable.
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.
Daytime Running Lights
Not all lights are created equal. Bontrager and Trek Daytime Running Lights are designed to be visible whenever you ride, day or night.
