No headlights. . .

[Mike Quillici]

I drove to work today, and my headlights worked. I then drove to a meeting, and my headlights worked. Then I left my meeting, and no headlights. My tail lights work, side marker lights work, high beams work, dash lights work, dome light works, but no headlights.

So, I drove home with my high beams on. Alas. My question, though, is this likely a switch issue? What's the best way to track down this electrical gremlin?

Thanks
