Ford F 150? I have an 03 Ford F-150. My left tail light does not work however the brake and blinker work. I changed the bulb and checked the fuses. No problem. There is no visible sign of wire damage. I was told to make sure both filaments on the bulb were good in case I got a bad bulb. After putting the bulb in the other tail light that works fine, I have concluded it was not the bulb. Everyone I have consulted is at a dead end and if I get pulled over again, the officer will give me a fine. So I come to Yahoo in the hopes of a corrcet resolution! Please help!
