Garmin Varia™ RTL516 – Bike Light Radar

The Garmin Varia™ RTL516 is the ultimate radar bike taillight for riders who value safety and visibility.

Increase safety with a radar bicycle taillight

A radar bike taillight like the Garmin Varia RTL516 adds a whole new dimension to safety. The built-in radar detects cars and other vehicles up to 140 meters away and sends alerts directly to your compatible Garmin device or the Varia app on your phone. This allows you to prepare before a vehicle approaches and adjust your position on the road.

Powerful rear light with high visibility

With a light output that can be seen up to 1.6 kilometers away in daylight, the Garmin Varia RTL516 serves as both a powerful taillight and an advanced safety system. The light has multiple modes—including steady and flashing—so you can choose the setting that best suits the conditions and battery life.

Easy integration with your bike computer

Connection via ANT+ and Bluetooth

With both ANT+ and Bluetooth connectivity, you can use the Radar bike taillight with multiple devices at once. This means you can have radar information on your Garmin Edge while using the Varia app on your phone – perfect for training, commuting and longer rides.

Long battery life for long trips

The Garmin Varia™ RTL516 delivers up to 9 hours of battery life in flashing mode and up to 6 hours in constant light. This means you can confidently use it on both short and long rides without worrying about the light failing midway. Charging is easy via USB.
