Princeton Tec has a new tail light dubbed the “Swerve” that is designed to compete with the popular Planet Bike Superflash. It features two high-powered LEDs (one with a diffused beam, the other with a focused beam), and two modes (one steady and one flash). It comes with a versatile mount that works on a fork, handlebar, seatstay, or seatpost, and it has a built-in clip for mounting on a helmet, jersey, or seat bag.
The Swerve, with its pair of 0.5 watt LEDS, should be brighter than the Superflash. I’ve seen side-by-side video beam shots comparing the two and it appears the baseline output of the Swerve may be brighter, but the strobe flash of the Superflash is definitely more eye-catching and intense. It just goes to show that there’s more to a light than numbers on a spec sheet. I was planning on picking up a Swerve, but after seeing the beam shots, I think I’ll stick with my Superflash for now. At $24.95 the Swerve is a great deal and a viable alternative, but it doesn’t look like Planet Bike has too much to worry about quite yet.
