Rear Turn Signal Replacement on a 2021 Ford F-150 Tremor 3.5L V6 Turbo

This video shows you how to replace a burnt out rear turn signal on your 2021 Ford F-150. We recommend that you change both the driver and passenger side bulbs at the same time on your F-150 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-150's way of telling you that the bulb is burnt out. Turn your hazard lights on and check the front of your F-150 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-150, be careful not to touch the glass portion of the bulb with your fingers as this will cause the bulb to burn out prematurely.
