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 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.
