Princeton Tec Swerve LED Light

Product Code
Princeton Tec
Current Stock

A combination of a diffused lens (on top) and a collimated focused lens (on bottom) creates a very bright 180-degree beam pattern than alternates between a wider beam and a narrow beam. Since the eye must juggle these two beams, it doesn't get a chance to relax, resulting in a very high level of visibility. The toggle switch makes it easy to turn on and off even with gloves on. Handle bar, seat post, seat stay and fork mounts are included, and the built-in clip allows for attachment to your helmet, pack or messenger bag. Rear light.

This light is great! I probably have 50 hours on the original batteries and it is still going strong, but I do use it only in flash mode. I like the design as it concerns the on/off/flash switch because it is easy to manipulate. It is mounted rear facing on my seat tube, which on previous lights, was difficult to manipulate when riding. Yes, I often forget to switch it on before starting a ride.

best battery powered light

I decided I needed a better rear light after riding with two friends on Southern Tier Route in October (Austin TX eastbound to New Roads LA + off route to Denham Springs LA). Rainy, overcast and shady portions we were using our lights to give drivers notice we were there. My old light wasn’t even visible to my riding buddies. This one is VERY bright, and impossible to miss. Easy mounting, Looking forward to being seen this riding year!!!

Great light

Very bright. My son saw it flashing from at least 1/4, maybe 1/2 mile away. Solidly built.

Bright and easy to use

This light stands out very well in low and normal visibility. It's easy to use and has a number of different mounting options. Excellent light.
