Abrégé anglais

Embodiments of the present disclosure include a decorative light string including a first light strand, a power supply, a controller, and an electrical connector. The first light strand includes a plurality of parallel connected light emitting elements. The power supply is configured to convert alternating current (AC) line power to direct voltage (DC) voltage power to power the first light strand. The controller is operatively coupled to the first light strand and the power supply. The controller is configured to control the plurality of light emitting elements. The electrical connector couples a first light strand to a second decorative light string via the AC line power.
