Hello all. I just plugged in LED bulbs (from 42 Draft Designs) for the rear plate light and I noticed tonight when the car is off the bulbs dim and don't go completely off. When the light switch is turned on they brighten as they should. I reversed the bulb but I think LED's have a polarity something-or-other so reversing them didn't work so they only go in one way. I re-installed the stock bulbs and they work as they should; meaning the light switch is off the bulbs are off, the light switch is on the bulbs are on. Any ideas?
