Abstract
A bicycle light has in one embodiment a mounting base to connect to the bicycle, and an LED light unit for insertion into and removal from the base. The light unit includes a printed circuit board with LED driver and a rechargeable battery, all of which are encapsulated by a direct overmolding that forms a casing for the unit. For charging the light unit is pulled out from the base and plugged into a USB port via an extending USB blade. A motion detector on the PCB shuts off the LED if no motion is detected for several minutes, thus eliminating need for any exterior switch. Another embodiment is without the USB blade, with the battery charged by inductive charging.
