The Varia RearVue 820 is Garmin's rear light with a built-in camera and radar, so it records what happens behind you while warning your bike computer or phone about approaching traffic. The camera is the headline addition over the radar-only Varia units, and the light reaches up to 2 km of visibility with 25 lumens in solid mode. Battery life runs from about 10 hours in solid mode to 24 in day flash, and up to 30 with the light off. It suits road riders and commuters who want evidence after a close pass and a warning before one, and it costs more and runs shorter than a plain tail light.
