Procedure notes
This video shows you how to replace a burnt out rear turn signal on your 2012 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.

本视频演示如何更换您 2012 福特 F-150 车辆的烧坏的后转向灯。 我们建议您在维修您的 F-150 时，同时更换驾驶员侧和乘客侧的灯泡，因为灯泡随时间会变暗，如果其中一个损坏，另一个也可能会很快烧坏。 如果转向灯（也称为闪烁灯或闪光灯）快速闪烁、完全不闪烁，或者在打开时灯亮但不闪烁，这是F-150在告诉你灯泡已烧坏。 打开危险警示灯，检查F-150的前方和后方， whichever side 不亮的是灯泡烧坏的一侧。
更换 F-150 的转向灯灯泡时，请勿用手指触碰灯泡的玻璃部分，否则可能使灯泡提前损坏。
