Daytime Running Lights

If you only do one thing, do this

Studies show riding with a flashing, daylight-visible light is the single best way for a cyclist to increase the likelihood of being seen by a driver.1

After I put on the tail light, (drivers) respect me more, they give me more space when they have to pass me... I tell everyone I know to put lights on the bike.

What makes a light a Daytime Running Light?

Not all lights are created equal. Brightness is important, but it takes more than a lot of lumens to make an effective Daytime Running Light. A true DRL is designed with specific focus, flash and range to be seen from a meaningful distance during daylight hours. Without these three things, you just have a light.


Most bicycle lights use a steady flashing pattern. This pulsing is less noticeable than one that continually varies its intensity and pattern. The Day Flash setting featured on Bontrager Daytime Running Lights was created specifically to increase noticeability with varying outputs and an interruptive flash pattern.


Creating a light visible in daylight requires intentional design. By directing or amplifying output, we intensify the beam and extend its range. Without this, a light may appear bright in your hand but may not be noticed in daylight by a motorist on the road.


The earlier a rider is seen, the more time a driver has to react and pass safely. Bontrager Daytime Running Lights are detectable from a greater distance than standard lights. Every model in the line-up is made to be seen from at least 400 m away, and select models are designed for visibility from over 2 km, even during daylight hours.

Studies show that when you use a flashing tail light during the day, you’re up to 2.4x more noticeable than a rider using no lights at all (and up to 1.4x more noticeable than a rider using a light in steady mode).1 Bontrager Daytime Running Lights use an interruptive flash pattern designed to stand out specifically during daylight conditions.

Daytime Running Lights make a difference

Research shows a 33% decrease in accidents for bicycles fitted with Daytime Running lights.2 There’s a similar trend in both cars and motorcycles that use DRLs, with 25% and 13% drops in collisions respectively.

Stand out when you’re sharing the road

Studies have shown that 8 out of 10 cycling accidents occur during daylight hours, when most people are riding and driving.3 Daytime Running Lights are the single most effective product to help increase your noticeability during these peak hours.1
