I need to replace my plate lights so I could get my 2000 Ford F150 inspected. When I put the bulbs in, turned on my headlights to make sure I got them working. I have now taillights now & when I turned off the headlights. My headlight would not go off. They only way to get them off is to take my battery cable off. I have brake lights & blinker light, but no park light. How can I fix this?
