See and be seen with Serfas' USL-1 USB Headlight. It has steady, flash and low-beam modes, runs for up to 6.5 hours and is easy to install and remove thanks to the built-in universal quick-release rubber strap. Recharging the light's battery is simple and convenient, too. When the battery indicator tells you it's time, just plug the light into your computer's USB port.

This is a great light for being seen. Affordable and easy to fasten and unfasten to any post or handlebar on your bikes. It isn't really bright enough for seeing where you are going at night but if you just need an inexpensive flasher for others to see you, the lens LED works really well. I've used mine almost daily for a year and it still works great and the battery life is as long as when it was new.
