Garmin Varia RTL515 Rear Light

The Varia™ RTL515 rearview radar provides visual and audible warnings for vehicles approaching from behind up to 140 meters away.

This radar works perfectly with the Edge cycle computer or a compatible smartphone and with some Garmin wearables or even with the optional radar display.

This smartphone app helps you improve your awareness of your surroundings by providing images, as well as audible and vibrating alerts, indicating the location and speed of approaching vehicles.

When used with a compatible smartphone, the radar integrates with your favorite apps, like Ride with GPS to overlay rearview radar alerts on maps.

Alert motorists to your presence as early as possible with daytime visibility up to over 1.5 km.

Easily mount this compact and stylish device to the seat of almost any road bike. The upright design leaves more legroom and allows for unobstructed pedaling.

The Varia™ RTL515 includes multiple modes, including Group mode, which emits a low-intensity flash that doesn't disturb the vision of other riders in the group.

The time spent charging is not as important as the time spent riding the bike. Up to 16 hours of battery life in daylight flash mode and up to 6 hours in steady mode.
