Any solution for LEDs?

Just double-checked and used the same method for two different LED strings - a 120V one, and one that uses a 30v stepdown transformer. Same method seemed to work for both of them. The only caveat was (and I'm assuming this was due to bridge rectification) that one of the strings didn't want to reverse the flow of current when I turned the plug upside down - so, had to end up working from the far end of the light string, rather than from the bulb closest to the plug. Also, I'm assuming that this method will not work with a USB powered light string, as the voltage may probably be too low.
