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

Sachet Instructions
1. Grab your empty old bottle of Muc-Off. (You may need a pair of adjustable pliers to remove the trigger from the bottle). Or purchase our Bottle for Life.
2. Fill up to the shoulders of the bottle with 1 litre of lukewarm water for faster formula activation!
3. Carefully cut one corner of the sachet open along the diagonal cut lines.
4. You can carefully pour the sachet straight into the top of the bottle. Or using the box, fold the inside of the lid together using the printed lines as a guide and use this as a funnel to pour the powder into your bottle. (Please see our video for full instructions on this.
5. Screw your spray trigger back onto the top of the bottle. Ensure it’s tight!
6. Shake the bottle vigorously for 30-60 seconds to activate the formula. If you notice any undissolved powder simply keep shakin’ it!
7. Go clean that filthy bike!
