- IPX7-rated water resistance for reliable performance in wet weather.
- Weight and size: compact design at 98.9 × 25.9 × 43.2 mm and about 90 g, designed to fit road and gravel bikes.
- Brake light functionality automatically signals deceleration when you slow or stop, improving rearward awareness.

Data Insights
In real-world riding scenarios, RearVue 820’s combination of a powerful rear beacon and extended radar reach meaningfully increases rear-vehicle awareness. The system can identify approaching cars at up to 175 meters and convey their size and trajectory to you, while the tail light remains visible at distances up to 2 km. With Day Flash delivering bright daylight visibility (up to 100 lumens) and radar-only operation offering up to 30 hours of endurance, riders can rely on extended safety coverage during long commutes or endurance events. This integrated approach typically reduces sudden braking events from unseen vehicles and provides clearer situational feedback on supported Garmin devices.
Usage Instructions
Mount the RearVue 820 on your bike’s seat post using the appropriate Garmin mounting kit (sold separately), then pair it with compatible Edge computers or the Varia app. Choose your preferred light mode for daytime visibility and enable radar alerts to receive vehicle alerts on your display or smartwatch. For best results, keep firmware updated and ensure the device is properly aligned to maximize the radar’s field of view and the light’s coverage during rides in urban traffic or rural corridors.
Design & Material
The RearVue 820 combines a bold, high‑visibility rear light with a compact radar module in a rugged, weather-ready shell. The unit is engineered for reliability in varied conditions, with a clean, low-profile silhouette that mounts securely to most road and gravel bikes. Its front-facing radar sensor and bright tail light work in harmony to deliver timely, actionable feedback while staying out of the rider’s way when not needed.
- Dimensions: 98.9 × 25.9 × 43.2 mm
- Weight: roughly 90 g
- Water resistance: IPX7 rated for wet rides and splashes
- Power: USB-C charging for fast, universal compatibility
- Light patterns: Day Flash, Night Flash, Solid, Peloton with customizable patterns via app
- Radar coverage: 220° field of view for broad rear awareness
- Radar range: up to 175 m for approaching vehicles
Final Verdict
If upgrading your bike safety means fewer surprises on the road and clearer alerts from behind, the Garmin Varia RearVue 820 Radar Tail Light is a decisive choice. It delivers a brighter tail light, longer radar reach, and seamless Garmin ecosystem integration that makes real-time safety data easy to act on during every ride. Invest in RearVue 820 today and ride with heightened confidence, knowing you have proactive rear awareness at a glance and reliable braking signals that help drivers understand your intent.
