We installed some Diode LED Tape lights today in a master bathroom cabinet. The lights come on automatically when you open the door of the cabinet is opened. Doors are open and the LED lights come on automatically when you open the door with an IR switch. Doors closed and LED lights are off. Close-up of the IR Switch. Video of the lights turning on and off with the cabinet door.
