Research shows that using a flashing rear light visible in daylight is the most effective measure to increase the likelihood of being seen by drivers.

The compact yet bright daytime running lights from Bontrager and Trek feature a disruptive flashing pattern that is visible from up to 2 kilometers away during the day.

Studies have shown that using a flashing rear light increases your visibility during the day by up to 240% compared to cyclists without a rear light.

A true daytime running light has a concentrated focus, a striking flashing pattern, and a large range, allowing it to be noticed from a considerable distance during the day. Without these three characteristics, it is just a regular light.

When battery power drops below 5%, the brightness is also reduced to significantly extend the remaining battery life.
