Why did my tail lights stop working?
If only one of the tail lights appears to be out, the mechanic should check to see if the unlit bulb is burned out. Over time, bulbs will eventually fail and need to be replaced. The mechanic will check the filament in the unlit bulb to see if it is broken. If so, he or she will replace the bad bulb with a new one.
