Garmin Varia RTL515 and RVR315 Rearview Radar

If you want to ride smarter and be safer, the Garmin Varia RTL515 Radar Tail Light has your back! Mounted neatly on the seatpost, the Varia RTL515 performs double duty, acting as a taillight and as a sensor for vehicles approaching from behind.

The bright tail light offers daylight visibility up to a mile away. In addition, it is visible within a 220-degree range, so drivers can see you well before the radar sees the vehicle. The Varia RTL515 also provides visual and audible alerts to warn of vehicles approaching from behind up to 153 yards (140 meters) away.



This radar works seamlessly with your Edge bike computer or compatible smartphone as well as select Garmin wearables or the optional radar display unit.
