POSSIBLY A LOOSE GROUND WIRE AT LEAST THAT IS WHAT I AM LOOKING FOR ON MINE,GOOD LUCK! The most likely cause on the late 80's Bronco & Ranger for headlight problems is the failure of the Dimmer switch connection. I had to completely replace the connector & switch on my '88 Bronco II to resolve the problem.
