Supernova E3 LED Airstream Tail Light 2012 version
The Airstream Tail Light plugs into the power/charge port on the Airstream Head Light. Because it is so efficient, it only reduces the burn time by 10 minutes.
The light mounts to the seat post with a quick release O-ring.
The three red LEDs are extremely bright. Because of this, the Airstream Tail Light is not legal for use inside Germany. But we're not there. are we? ;-)
