So, I got a couple of LED light strips from ebay. I hooked them up to the city light light socket (the plug that's connected to the car and plugs into the city light housing) to make sure they work before mounting. Once I figured out the polarity, I noticed that even when the lights are off (switched off), the LED lights continues to glow, though much dimmer. However, the LED strip never go out. I don't think this is normal with the LED light strip. When I plug the regular city light/housing back in, the light bulb stays off until I turn the lights on. Any idea why this is happening?
