Abstract
Various embodiments provide a light emitting diode (LED) flasher bulb that provides a flashing function for LED string lights. The LED flasher bulb is inserted into any one of a plurality of connectors of the LED string lights, and is compatible with an alternating current power source. The LED flasher bulb alternates the LED string lights between an on state in which LEDs of the LED string lights are lit up, and an off state in which the LEDs are not lit up. The LED flasher bulb is able to continuously alternate the LED string lights between the on state and the off state according to a determined pattern independent of the AC signal generated by the AC power source being positive or negative.
