🚴♂️ Garmin Varia RearVue 820 (010-03180-00): Advanced Rearview Radar + Tail Light with Vehicle Threat Tracking and Brake Light for Cyclists 🚗💡
Riding on open roads or busy city streets is all about awareness—especially what’s happening behind you. The Garmin Varia RearVue 820 (010-03180-00) combines an advanced rearview radar with a bright tail light to help cyclists ride with more confidence. It alerts you to approaching vehicles with audible and visual warnings on a compatible Garmin Edge cycling computer, select Garmin smartwatches, or the Varia app on your smartphone.
With Garmin’s most powerful and precise radar tracking technology, RearVue 820 offers a wider field of view, detects vehicle size and threat level, and can even provide same-speed tracking for vehicles following behind at the same pace (tracking may be limited at slower speeds or when radar is obstructed by weather/objects). Add a tail light that’s visible from up to 1.24 mi (2 km) plus a unique brake light flash pattern, and you have a safety-focused upgrade designed for long rides and daily training alike.

What the Varia RearVue 820 Does (And Why Riders Love It) 👀🚴♂️
RearVue 820 is designed to solve two key cycling safety needs:
- Rear traffic awareness with radar-based vehicle detection
- Better rider visibility with a bright, attention-grabbing tail light
Instead of guessing whether a car is approaching, you get real-time radar alerts and a visual display of approaching vehicles when connected to your Garmin device or smartphone.
Advanced Rearview Radar: Detect Vehicles, Size, and Threat Level 🚗📡
This rearview radar uses Garmin’s most powerful and precise tracking technology to:
- Detect vehicles approaching from behind
- Provide visual + audible alerts
- Show alerts for small, medium, and large vehicles
- Indicate vehicle movement and threat level while riding (with compatible Edge or Varia app)
Same-Speed Tracking (When Available)
RearVue 820 can also identify vehicles that are:
- Following behind at the same speed, or
- Attempting to pass
Note: same-speed tracking may be limited or unavailable at slower speeds or when the radar cannot detect the road due to weather or obstructions.
Tail Light Visibility Up to 1.24 mi (2 km) 💡✨

It also supports multiple light modes so you can match your ride conditions—daytime training, night rides, group rides, and more.
Brake Light Feature: Unique Flash Pattern When Slowing or Stopping 🛑
RearVue 820 adds a cyclist-friendly safety detail: a brake light that displays a unique flash pattern to help alert motorists and riders behind you when you’re slowing down or stopping. This is especially useful in:
