There was even a guy on the 911 tech board that used to put together and sell a "relay kit" just for the headlights, but that was probably >15 years ago so there may be a new solution, but chances are that guy is not still around.

I didn't read through ^those^ threads, so I don't know if what's suggested is correct. I think the first one is actually a thread that Shaun started. One of them is many pages deep. I assume since it's such a common issue, that they all end up at the same point. The 911 tech board was always a great source of correct/accurate info in the past. I would assume that hasn't changed.
