Headlights, interior lights, all lights on vehicle flicker while driving on the highway. The vehicle does this when there is no apparent load on the electrical system (I.e. blower, defroster, ac, power seats, windows etc.) the lights become very dim and then bright again in the matter of a few seconds. This can be dangerous to vehicles in front of you and approaching as they believe they are getting "flashed" by your vehicle. It is very unnerving driving with this random occurrence.
