If you don’t want to be left in the dark, this super inexpensive light is for you. It mounts and unmounts very easily and when you lock your bike, you take off the bike lights, and there is nothing left on your bike for the light-snatchers to steal. When you unlock your bike, mount the bike lights back on within seconds and off you go. With these rechargeable USB bike lights, you can at least put a little bit of juice back in them while you’ve got them on hand. Mountain Equipment Co-Op sells these super-stripped-down versions, available in red or white, for $9.25; they charge through a micro-USB port with an accompanying cord, and come equipped with little indicator lights that tell you whether or not you are fully charged. It’s water resistant and does not require any replacement batteries. The USB rechargeable Lithium battery does not have a memory effect.
