Are you being seen?

Research shows that riding with a flashing, daytime-visible rear light is the single most effective measure a cyclist can take to increase their likelihood of standing out to drivers.* Bontrager Daytime Running Lights are designed with a specific flash, focus and range to make them more visible during daylight hours.


Many standard bike lights flash have a steady pattern. But lights that vary the frequency and intensity of their flash pattern can be more noticeable. The Day Flash setting on our DRLs uses an interruptive flash pattern with accentuated Lumen pops in order to more likely to be noticed during the day.


Creating a daytime-visible light requires intentional design. By directing or amplifying output, we intensify the beam and extend its range. Otherwise, a light may appear bright in your hand but won’t 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. Our DRLs are detectable from a greater distance than other standard lights. Every model is visible from at least 400 m away, and select models are visible from over 2 km away.

Which Flare rear light is best for me?

All Bontrager rechargeable Flare tail lights are Daytime Running Lights, which means they’re designed to help you stand out during all hours of the day and night, but the best option for you depends on where you ride.

Open roads

Flare RT is the best option for long-range visibility. This tail light has 90 Lumens of output with a distinctive flash, focus and range for visibility from over 2 km away during daylight hours, a 12-hour run-time in all-day flash mode, and wireless connectivity so you can control it from a computer or remote.

City streets

Flare R City is a more compact tail light that’s best suited for use in and around the city. It has 35 Lumens of output with a distinctive flash, focus and range designed for visibility from 900 m away during daylight hours. It also has a wider beam that’s best for city streets, where side-to-side visibility can be more important than long-range visibility.
