To make a Christmas LED light flash, you can use a blinker bulb or attach a flasher unit to your string of lights. The blinker bulb is designed to fit into a standard socket and will interrupt the power flow periodically, making the lights flash. Alternatively, a flasher unit, when connected to the light string, achieves the same effect by cycling the power on and off.
