I was not aware that headlights had circuit breakers or fuses. I just thought it was a safety measure to not have Denny's trouble while driving. While in college I had an old 63 Plymouth, former LA County sheriff's vehicle. The lights would not go off while driving but if I turned them off for a few minutes when I stopped, they would not come back on until they were ready to come on. That might take 30 minutes or more. Never figured out what caused it but it sure made parking with a date handy. grin
