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

Bontrager daytime running lights are compact and powerful and feature an interruptive flash pattern that's daytime visible from up to 2km away.

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.

Lighter and brighter

The all-new Flare RT is compact and powerful. It’s 36% lighter than the original and features 40% more Lumens.

Ride longer with more battery life

Get a full 12 hours of runtime with all-day flash mode and feel secure in knowing there are 30 minutes of extra battery life built in for when you reach low power mode.

ANT+ and Bluetooth Smart

Connect to Garmin and Bontrager Transmitr devices for always on, battery status, and wireless control.

Daytime Running Lights

Not all lights are created equal. Bontrager Daytime Running Lights are designed to be visible whenever you ride, day or night.
