I tried to do LED and nothing was working. I thought crappy lights. Are you saying there's a trick to it?

Cheap LED PNP bulbs are polarity sensitive (like putting AA batteries backwards into your remote control doesn't work either). If you install a LED bulb and it doesn't work try to plug it in the other orientation.

Better quality PNP LED bulbs have a diode bridge circuit hidden inside that makes them work no matter how you plug them in.
