Accidents happen, but some can be avoided with a little preparation. The Portland Design Works Red Planet Tail Light puts you one step ahead of danger. Named for our bright red galactic neighbor, the Red Planet is also your ticket to not getting a light ticket.Portland Design Works' Red Planet Tail Light features a simple, no-nonsense design. It uses five LEDs to illuminate the darkness in your wake. Three of the LEDs point straight back into the eyes of drivers, while the two outer LEDs project outwards for side-to-side coverage. The lights are affordably powered by two AAA batteries, and the whole sub-50g system is housed in a durable, water-resistant plastic case.The Red Planet has three strobe settings -- steady, blinking, and 'kitt.' We're sure that you can imagine the actions of the first two, but 'kitt' was something new to us. This mode sweeps across the LEDs, side to side, much like the voice of a certain 1980s talking car of the same name. So, when you're a 'rider of the night', and you don't want to be just another blinky-blinky on the rode, you can activate this function to stand out to the inattentive driver.For easy attachment, the light comes with mounts for your seatpost and seat stays. PDW also included a backpack clip if you think that your bike is too pretty for mounting hardware.The Portland Design Works Red Planet Tail Light is available in one color and in 32x70x43mm size.
