It's hard to explain and I may need to make a video to show you guys what I am getting because it does one of three things 1. The light will stay on as if I am hitting the brake constantly 2. The light will stay on (dimmer like it should if the running like were on) but when I go to place it back into the headlight assembly it shuts off 3. The light just stays off which what was happening when I gave up on it last night. This is the problem I am getting.
