Abstract
An enhanced control mechanism for an LED light string system is provided for switching between one of two DC output phases or polarities so as to actuate one or the other of two LEDs within the bulbs on the light string. The control mechanism is further configured to allow switching so as to pass through the input power provided by a high-to-low voltage converter that is plugged into its electrical power feeding end. The control mechanism may then provide rectified AC voltage, or DC voltage, of various switched values to the LED string according to the particular needs of the LED bulbs.
