ABSTRACT:
A flicker light string suitable for unlimited series-connection, each light string including a driver and a plurality of series-connected lamps. The driver has an input end connected to an independent external power supply and a trigger circuit. The trigger circuit has an output end connected to the series-connected lamps and a trigger end reserved for connection to an external cord for acquiring an oscillatory signal to control the continuity and interruption of the trigger circuit, so that the light string can flicker with the oscillatory signal. Multiple units of the flicker light string can be serially connected to form an unlimited extending flicker light string, and all the connected light strings can flicker synchronously without the risk of being overloaded or overheated.
