I spent many years pulling a large stock trailer with lots of lights and finally cooked my headlight switch. I changed it out in the parking lot of an O'Reilly's. Some of the wires were slightly toasted as well.
My headlights were doing some weird things that night. So in answer to your question, yes, I would say a bad headlight switch could be your problem.
