Princeton Tec Swerve Tail Light

It might not be stealthy, but anyone who bikes in traffic knows the value of being seen, especially during the first dark evenings of rush hour each fall.  But rather than wearing a bright yellow vest adorned with reflectors, opt for Princeton Tec’s Swerve Tail Light.  This simple yet functional device boasts two settings—a solid  glow and a flashing pattern that casts out a 180-degree strobe—via a simple switch that’s easy to trigger, sight unseen, while pedaling.  Two AAA batteries power the twin half-watt Maxbright LEDs for up to 70 hours, and the built-in clip means you can attach the light to your helmet, bag, or back pocket.  What’s more, the revolutionary (yet oh-sooooo-simple) mounting system, which is composed of a rubber band that wraps around two anchors on the light, lets you mount the Swerve pretty much anywhere on the bike, from seat post to handle bar to fork mount to seat stay.  See, you just ran out of excuses for not using one.
