Princeton Tec Swerve

The Princeton Tec Swerve will not win any tail light innovation awards but it does have a couple things going for it.

First, the light output is highly visible. Rear visibility and side visibility are excellent and the flashing mode has very good animation as the light seems to dance between back and side LEDs.

Next, the switch is a basic directional switch where flipping it up puts it in solid mode and going the other direction puts the light in flash mode. The switch is oversized as well and it makes it very easy to operate the light even with gloves on and in all-weather conditions.

The only downside really is the light is not rechargeable. It will run out of battery eventually and regularly if you are a bike commuter. Alkaline batteries can get expensive and they are often tossed in landfills. The Swerve operates on 2 AAA Alkaline batteries.

Video: Test with the Princeton Tec Swerve Tail Light. Tail Light was shot from 20 yards away with a camera at fixed exposure. The light was pointed at the camera then turned to the side. Different flash modes were activated.

    Do the reviewers understand that there are rechargeable AAA batteries? And that these can be replaced once the batteries go bad hundreds of cycles later, unlike built in USB rechargeable ones?

  • Rob says:

    Use the eneloop rechargeables. Best quality out there right now.

  • Cedric says:

    I’d prefer AAA over internal Li battery any day. Eneloops last a long time between charges and they can be replaced. Li batteries last only a few hundred cycles – much shorter lifespan than the LEDs in the light!

  • ray allen says:

    I agree with Rob – I use rechargeable AA and AAA batteries so I can carry a spare set of batteries so that I don’t have to ride home in the dark.

    As far as brightness, the description is subjective.

    I want to know what the lumen output is so that I have a way to compare different tail lights.
