Flagship rearview radar tail light
Garmin Varia RearVue 820 Radar Tail Light
Garmin's newest and brightest radar tail light, with a 60 GHz radar that sees further and wider than the RTL515 and can classify vehicle size and lane changes. It also brings USB-C charging and a user-replaceable battery.
Highlights
Why we rate it
Longer, wider radar
A 60 GHz radar spots vehicles up to 175 m back across a 60-degree beam, so traffic on curves and wide roads is picked up earlier.
Vehicle threat detail
Indicates vehicle size (car, truck, motorbike), lane changes and same-speed vehicles on compatible Edge units.
Brightest Varia tail light
100 lumens in day flash, visible from up to 2 km, with 220-degree visibility.
Better battery
Up to 24 hours in day flash and 30 hours radar-only, charged over USB-C; the battery is replaceable.
Broad compatibility
Works with Garmin Edge and watches, the Varia app and third-party head units over ANT+ and Bluetooth.
