Serfas USL-3 USB Headlight

Stay safe and enjoy after-dark rides 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 its USB Smart Charger.
