Yeah my interior led next to the headlight switch continuously blinks when I turn on the headlamps....it does not however when I just turn on the eyes or fogs. (it doesn't blink for the first 5 or 10 seconds but then blinks non-stop as long as I keep the headlights on) I'm thinking it may have something to do with the heatsink falling off during the install. It was loose apparently when I got it so I may be dealing with a bad connection.
What is wrong with unplugging the battery? Will it screw stuff up?
