The Princeton Tec Swerve rear bike light uses 2 high-powered LEDs and alternating beam patterns, resulting in a very high level of visibility.

  • A combination of a diffused lens and a collimated focused lens creates a very bright 180° beam pattern that alternates between a wide beam and a narrow beam
  • Because the eyes must juggle these 2 beams, they don’t relax and therefore, the light always remains highly visible
  • 2 lighting modes: flash pattern or a steady light
  • On/off toggle switch extends beyond the perimeter of the light for easy use while on the bike
  • Abundant mounting options: handlebar, seatpost, seatstay and fork mounts are included; plus, the built-in clip allows for attachment to your helmet, pack or messenger bag
  • Swerve is resistant to heavy rain, heavy splashes and even the occasional dunking
  • Light output equivalent to 7 lumens
  • Includes 2 AAA batteries

Imported.

    Comments about Princeton Tec Swerve Rear Bike Light:

    I bought this after I saw a magazine review. I figured,hey,*two* 1/2 watts. That's twice what my Planet Bike SuperFlash has. In practice though,it could be alot brighter.

    First the bad news. Only one of the LED's is really bright. The second one is hampered by a diffuser. The idea is it's supposed to shine the light out to the sides for wider visability,but all it does is dull it. They should either redesign the duffuser,or replace the second 1/2 watt with regular side LED's. Beyond this,it's all good. The switch rocks. It's a large lever that it easy to use and allows you to tell by touch if the light's on or not. It can also be flipped around for left or right hand use. The clip on the back of the light is large and has gripper teeth to help it stay put. And the strap mount is really sweet. It uses a big O ring to wrap around the seatpost to hold the light in place. It comes on/off the bike in seconds with no adjusting for seatpost size. This lets you move it from bike to bike quickly and easily. It also makes it a snap to remove/install the light when locking up. This is one of the better mounting systems I've used. Battery life is good and the light is totally waterproof.

    If PT could sort the second 1/2 watt out,this could be a SuperFlash killer. But it still makes an excellent light for urban riders or people with multiple bikes.

      Comments about Princeton Tec Swerve Rear Bike Light:

      I got this light to make myself more visible to traffic during daytime riding. It is highly visible in bright daylight at a considerable distance - even more so in shadow conditions.

      Since I've been using it, I notice that drivers stay way the frick away from me. Once someone went all the way into the opposing lane to pass me, nearly causing a head-on collision - nice.

      The bracket mount did not work anywhere on my bike because it has no round tubes (Kestrel frame) so I just use the pocket clip to mount it on the seat bag. That works great and puts it higher anyway.

      You will not be disappointed

        Comments about Princeton Tec Swerve Rear Bike Light:

        We recently completed a 600km ride in 38 hours of mostly pouring rain. All of my lights had major water leakage, however due to the mechanical switch on this light it continued functioning fine. I just shook out the excess water every time I changed the batteries. The Planet Bike super blinky eventually stopped working when the push button switch was fully soaked. The PT Swerve also uses even less power than the Planet Bike super blinky, even with two steady emitters. The PT uses 50mA well regulated down to about 2V, which is clearly way less than 1/2 watt per emitter. The Planet Bike Super blinky is not regulated and starts very bright at around 1/2 watt with alkaline batteries at 3V, but quickly drops to around 65mA at 2.5V with NiMh batteries. It appears that the PT Swerve might have more modern emitters since they are running less than half the current of the Planet Bike light with similar brightness, although that is pretty subjective.

          Comments about Princeton Tec Swerve Rear Bike Light:

          Rear light is easily the best I've used, as it's easily visible, and durable enough for long night rides (thirty-five miles) through rough roads of a major city. Compared side by side with knog bullfrog and skink, and Prince tec RF6; this is the best of the best.
