This happened repeatedly one night, many times, then several weeks later instrument lights brighten while driving. Was scared headlights would shut off. What could this be?

    Would suggest have your alternator tested - sounds like the regulator is having a bad day. Overcharging the electrical system.

    Have the headlight switch and the wire connector to the switch checked for signs of arcing (blackened terminals) or melted plastic.
