Varia RearVue 820 Radar Tail Light

What Our Gearhead® Experts Are Saying:

"The wider detection range and clearer threat differentiation make this a serious upgrade for high-speed road riding. I like pairing it with an Edge head unit so I can see vehicle distance and movement in real time."

High-speed road riding demands real-time awareness, and the Garmin Varia RearVue 820 Radar Tail Light delivers advanced rear detection in a compact system. Designed for performance road and gravel setups, it combines extended radar range with a powerful tail light to increase rider visibility and situational awareness.

The updated radar tracks vehicles approaching from up to 175 meters away with a wider field of view, providing earlier alerts through compatible Edge cycling computers, the Varia smartphone app, or select Garmin smartwatches. Riders can see vehicle size classification and lane changes when paired with the latest compatible devices. Same-speed tracking enhances awareness of vehicles pacing behind. A high-output tail light is visible from up to 2 kilometers and includes an integrated brake light that automatically changes flash pattern during deceleration. With up to 24 hours of battery life in day flash mode, four light pattern options, and customizable settings in the Varia app, the RearVue 820 adapts to training rides, group sessions, and endurance events. A redesigned seatpost mount ensures clean integration on most road and gravel frames, making it an essential safety upgrade for riders who log serious miles on open roads.
