Question
02 lincoln continental, rr tailight has two bulbs for brake/blinkers. One bulb stopped working and replacing it did not help. Car is 45K mile vehicle and immacualte...please help!

Answer
You have three possibilities. The first would be the tail light assembly is defective. The second is the turn signal switch is defective. The third, and most likely culprit would be the flasher. It is the cheapest, and is where I would start. Also, sometime if the front light is bad, given that they are on the same circuit, it will make the rear not work.
