Garmin Varia™ RearVue 820 Radar + Rear Light

The Varia RearVue 820 features the most powerful and accurate radar yet with a wider field of view, giving you more reliable alerts than ever before. The rear light offers up to 2 km of visibility and features a brake light that activates when you slow down or stop.

Powerful and reliable radar - With the most powerful and precise radar tracking technology, Varia RearVue 820 radar detects vehicles approaching from up to 175 meters (more than 190 yards) away with a wider field of view.

Bright Tail Light and Brake Light: Garmin brightest tail light means you’ll be visible from up to 2 km (1.24 miles) away. A brake light detects when you’re slowing or stopping and displays a unique flash pattern.

Advanced Vehicle Tracking: See alerts for small, medium and large vehicles, and see when a vehicle changes lanes, along with its threat level — when riding with the latest compatible Edge® cycling computers or the Varia™ app on your smartphone.

Gar Alerts Your Way: For visual and audible alerts while you ride, connect this radar to the Varia smartphone app, compatible Edge cycling computers or Garmin smartwatches. In addition to haptic alerts on your wrist, select Garmin smartwatches can also give voice alerts for approaching vehicles — this feature is currently available in the Garmin Public Beta program for select smartwatches3.

Variety of Light Pattern OPtions: Ride with four different light patterns: day flash, night flash, solid mode and peloton mode, which helps preserve the eyes of riders behind you. Create your own custom light patterns in the Varia app on your smartphone.

Compact Design: A sleek, compact design and new seatpost mount means Varia RearVue 820 fits cleanly onto almost any road or gravel bicycle and is compatible with the Varia seat rail mount kit (sold separately).
