Electrical Guru's Please help!!!!!!

I have a huge problem with my headlights. When I turn them on they flicker on and off. Then stay on for a few seconds then go out again. Both do it at the exact same time. I'm thinking a loose connection some place where they join together. Do our light switches go out? So for those who have gutted their engine bay(oink) or anyone else who has had this problem before please help me out. I can't drive my car at night b/c everyone I pass thinks I'm flashing my lights on and off at them. I do have aftermarket headlights and bulbs but, I don't think that is the problem. Thanks.

Thanks for the help. I'll check it out now while I still have day light. If the bulbs are pulling more watts, wouldn't all of my lights dim? Thanks again.

Well, I'm pretty sure that I found the problem. On the back of the headlight switch is a grey plastic cluster with wires going into it. The brown wire was severed a little and the hole that the wire went into was melted and cracked. So that grey piece has to be replaced. I cut the wire and spliced in a new piece. Put it back together and it seemed to have fixed it. Well after about 15 minutes they started to flicker on and off again. I hate electrical problems. And this one is getting old fast. I noticed that the wire would get hot to the touch before I spliced in the new one. Does this mean that my headlights are drawing to much juice for my stock system to keep up? I plan on replacing the plastic piece. I'm just looking for a quick fix until I can make it to the junk yard. Thanks for the help.
