Yesterday while at a squirrel dog trial, my buddies wife backed into my truck and smashed the drivers side tail light. Their insurance is covering it but they can’t get me an appointment until the 17th and I need my truck until then. The bulb looks okay but it will not light up. The passenger side tail light will work one minute and then not work the next. Any suggestions for a quick & easy fix to get at least one brake light working until my appointment with the auto body shop?
