Pulling double duty as both a powerful 200-lumen headlight and dazzling 40-lumen tail light, the Blackburn 2Fer XL USB Light is made from a tough alloy body that houses optimized lenses and powerful LEDs that cast enough light to easily be seen by traffic, but also show you exactly where you are riding in the front. The clever mount design allows you to quickly pop it onto your bike's handlebar or seatpost, but also has a clip to mount on your backpack, belt, or shirt. This versatile light also does away with the hassle of disposable batteries by charging via an included Micro-USB cable, and features waterproof functionality up to IPX-6 standards to keep you shining even in the rain.
