操作说明
本视频演示如何更换您 2009 GMC Envoy 车辆的烧坏的后转向灯。 我们建议您在维修您的 Envoy 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Envoy在告诉你灯泡已烧坏。 打开危险警示灯，检查Envoy的前方和后方， whichever side 不亮的是灯泡烧坏的一侧。
更换 Envoy 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。

This video shows you how to replace a burnt out rear turn signal on your 2009 GMC Envoy. We recommend that you change both the driver and passenger side bulbs at the same time on your Envoy 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 Envoy's way of telling you that the bulb is burnt out. Turn your hazard lights on and check the front of your Envoy 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 Envoy, be careful not to touch the glass portion of the bulb with your fingers as this will cause the bulb to burn out prematurely.
