Garmin unveils Varia RearVue 820, its brightest and most powerful radar tail light for cyclists
With advanced vehicle tracking, superior battery life and a brighter tail light than ever before, cyclists can ride with greater peace of mind

Malaysia, 4 February 2026 – Garmin Malaysia today announced Varia RearVue 820, its most innovative radar tail light that can help cyclists be more aware and visible while riding on the road. This new advanced vehicle tracking detects a vehicle’s size, side-to-side movement and categorizes threat levels as the vehicle approaches from behind with alerts displayed on compatible Garmin cycling computers or the Varia smartphone app.
Powered by more precise radar technology, the Varia RearVue 820 is Garmin’s brightest radar tail light and serves as a brake light when riders slow or stop, improving visibility to motorists and other cyclists. With superior battery life of up to 24 hours in day flash mode and up to 30 hours in radar only mode, cyclists can ride even longer with greater awareness and peace of mind.
“We’re excited to expand our trusted cycling radar technology with Varia RearVue 820. Whether cyclists are commuting by bike to work or training along busy streets, this radar can help them stay more conscious of nearby traffic, especially with new, innovative advanced vehicle tracking alerts, all while the brilliant tail light and brake light can help them be more visible.”
– Mr. Scoppen Lin, Assistant General Manager, Garmin Asia.
Advanced vehicle tracking
When riding with a compatible Edge cycling computer or when paired to the Varia smartphone app, cyclists will receive visual and audible alerts as vehicles are approaching or changing lanes behind them, along with their threat level indicating if the approaching vehicle is a higher threat to the cyclist based on its speed or path of travel. New vehicle size detection also provides visual alerts identifying the size of approaching vehicles as small, medium or large, displayed directly on the Edge cycling computer or in the Varia app.
Greater peace of mind on every ride
- Boasting a wider field of view, the radar can detect vehicle movement several lanes away and alert riders on their compatible Garmin smartwatch, Edge cycling computer or the Varia app.
- Powerful radar technology allows the device to detect vehicles from over 170 metres away.
- With same speed tracking1, riders are notified about vehicles that are following behind them at the same speed or waiting to pass.
- In addition to vibrating alerts on the wrist, select Garmin smartwatches can also deliver voice alerts for approaching vehicles. This feature is currently available in the Garmin Public Beta program on select smartwatches2.
Greater visibility on the road
Ride with greater confidence day and night with Varia RearVue 820’s bright tail light, visible from over 2 kilometres away and offers multiple light mode options, including day flash, night flash, solid mode and peloton mode. Cyclists can also create their own custom light patterns in the Varia app based on the needs of their ride, including brightness level and duration of flash. Adding to that superior visibility, the device detects when the rider is slowing down or stopping, then alerts others on the road with a unique, flashing brake light pattern.
Compact design
Featuring a sleek, modern design, Varia RearVue 820 includes a USB-C port for convenient charging and a new seat post mount that fits securely and cleanly onto almost road or gravel bikes.
