Rear Turn Signal Replacement on a 1991 Ford F-350 Custom 4.9L 6 Cyl. Crew Cab Pickup (4 Door)

This video shows you how to replace a burnt out rear turn signal on your 1991 Ford F-350. We recommend that you change both the driver and passenger side bulbs at the same time on your F-350 as they get dimmer over time and if one is out, then the other one is likely to burn out soon. If the turn signal (also known as a blinker or flasher) blinks rapidly or doesn't blink at all or lights up without blinking when it is turned on, this is your F-350's way of telling you that the bulb is burnt out. Turn your hazard lights on and check the front of your F-350 and then the back, whichever side is not lighting up is the side with the burnt out bulb.When changing the turn signal bulb in your F-350, be careful not to touch the glass portion of the bulb with your fingers as this will cause the bulb to burn out prematurely.
