Garmin Varia RTL515 Rearview Radar Tail Light



This rearview radar with tail light pairs with your Edge® bike computer or compatible smartphone to alert you of vehicles approaching from behind. Varia RTL515 rearview radar provides visual and audible alerts for 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. This smartphone app helps you increase your awareness by providing graphics - plus tone and vibration alerts - that indicate the position and speed of approaching cars. When used with a compatible smartphone, Varia radar integrates with your favorite apps, such as Ride with GPS to overlay your maps with rearview radar alerts. Alert motorists to your presence as soon as possible with daylight visibility up to 1 mile. Easily mount this sleek, compact device on the seatpost of almost any road-use bicycle. The vertical design allows for better leg clearance and a perfectly comfortable ride.
