Overview

How Does the PDW Asteroid Taillight Work?

The PDW Asteroid Taillight is a minimal, USB rechargeable tail light that mounts in seconds and shines super brightly with high quality optics so you can be seen. You double click the lens to turn it on or off, which prevents accidental ons and offs. With the light on, a click moves through On, Pulse and Flash modes, and it remembers the last mode you used.

PDW lists up to 35 hours of runtime in Flash mode, 6.5 hours in Pulse and 4.5 hours in Steady. It charges from depleted to full in 2 hours 15 minutes with the included Micro USB cord, and the weatherproof exterior is made for all season riding. It weighs 76 g (2.7 oz).
