How long should it take the light to be fully charged?
Mine takes anywhere from 2-3 hours, depending upon the status of the battery. You may already know this, but it has a little LED charge status light on the underside of the unit. It will change from red to green as it charges. Red indicates low charge, blinking green indicates partially charged, solid green indicates fully charged. Once it is fully charged, it lasts for weeks, as long as you remember to shut if off when you hop off the bike ;)
