Protect yourself from being hit on the bike at night with the Garmin Varia Radar Tail Light.

The world's first cycling radar, the Garmin Varia helps create a safer cycling environment by warning approaching vehicles of a cyclist ahead by increasing in luminosity as the vehicle approaches. The Varia system works independently or integrates seamlessly with compatible Edge cycling computers; an Edge computer or the Varia head unit can show multiple approaching vehicles and indicates the relative speed of approach and threat level.

The threat of getting hit from behind by a car or truck is real. That’s why getting some extra help knowing what’s sneaking up behind you is an important breakthrough. You already use caution and check over your shoulder, especially before making turns, but Varia radar gives you an important tool by watching behind you even when you aren’t.

The Varia line of cycling awareness products also includes Varia smart headlights and tail lights. When paired with select Edge bike computers, these bike lights help to create safer riding conditions by adjusting the beam focus point according to a bike’s speed and matching brightness to changing light conditions.
