As bright as they come, the unique shape of this taillight emits a vertical beam of LED light that makes you extra visible to cars and bikers. This taillight emits 35 lumens that, in laymens terms, means its really bright. We've been testing this light out and the comment we get the most is, "Wow. That is one bright taillight!"

The water-resistant, silicone body features unique straps that adjust in size allowing you to mount anywhere on your bike. The electronics are contained within the silicone housing and instead of running off a battery charge this taillight has a USB port that you can charge via computer or charger. This light has 4 modes including beam and blink, and in the lowest blink setting gets up to 9.5 hours of light on a full charge.
