Tired of attempting to stay green by peddleing to work or class only to know in the back of your mind that those bike lights are run by disposable batteries? Well no longer will feel guilty for such matters. Check out the Flea 2.0 USB rechargeable bike light.
The front light houses 4 super-bright LEDs capable of 40 lumens for up to 5 hours. The rear provides up to 12 hours of light, all from one single charge. As long as can make to a USB port within that time, you’ll be able to recharge. If not, then the kit also comes with a solar charger — just don’t expect to make a full charge before night sets in.
