The Garmin Varia RTL515 Radar Tail Light is way more than just a tail light. A tail light lets cars know where you are, but it doesn't let you know where they are. This little radar powered seatpost accessory syncs up to your bike computer or smartphone to alert you when vehicles are approaching from behind. It's compact and easy to hook up, both to your bike and to your electronics. Plus, the light itself is excellent, providing a maximum of 65 lumens with four different modes and up to 16 hours of battery life.
