I'm getting this Satellite back together and I've been checking the electrical. One thing that I have a problem with is the parking lights in the front bumper. They come on when I pull the switch to the parking position, but when I pull it all of the way out for the headlights they go off. I've cleaned the housings and the bumper to get a good ground but this problem is persisting. Is this a problem with the headlight switch?

Thanks
