I have an LED dome light that I would like to install, however the door switch seems to have no effect on it. It stays on 100% of the time when put into the factory dome light location.

The incandescent bulb operates just fine. I suspect there is just enough ground somewhere for the LED bulb to make use of and illuminate. Any ideas how to mitigate that?
