Planet Bike Blinky 1 Tail Light
The Planet Bike Blinky 1 Tail light is so named because it can be seen from up to one mile away. What's more, not one but three eXtreme LEDs give you a tail light with 220 degrees of visibility. Clearly, that's a tail light you want to have your back. The Blinky 1 has flashing and steady modes and up to 100 hours of run time on 2 N batteries, which are included. This ultra-compact tail light is weatherproof, comes with seat post and seat stay mounts and weighs a mere 59 grams with batteries.
