A shunt for bypassing LEDs in a series wired light string to keep the light string lit in the event of a failure of an LED. In one embodiment, the bypass shunt is a rectifier diode with a very high forward voltage drop (Vf). Another embodiment uses a transistor bypass device, where the collector and/or base is used as one terminal of the shunt device and the emitter is used as the opposite terminal. The preferred embodiment is to use the collector and emitter terminals only with the base terminal open.
