The Garmin Varia Radar Camera Tail Light combines three different features into one small package to help us stay safe when we're cycling out on the road. The Varia mounts to our seatpost and connects to our Garmin cycling computer. Once paired, the Varia's rearview radar tells our Garmin when cars are approaching from the rear. There is a built-in camera that continuously records and will automatically save footage if it detects an incident or close-call. There's also an integrated tail light with multiple modes to improve our visibility to traffic.
