I have 2 strings of LED lights on my patio wired to a switch/outlet combo. This is controlled by an interior switch that also controls my exterior door light. I can either just have the door light on or switch on the LEDs at the combo box. All was working well.
However, I just recently tapped into the end of the strings with a 16/3 exterior extension cord, cut off the female end and hardwired it into another switch/outlet to control some LED rope lights in a screened porch. When the rope lights are switched off, they continue to glow very dimmly - visible only after dark.
How do I stop them from glowing when they're turned off?
