Procedure notes
This video demonstrates how to change a burnt out taillight bulb on your 2009 GMC Sierra 2500 HD. Tail lights are also called rear position lights or running lights. Some of the other bulbs in the tail light cluster such as the brake light or turn signal may also function as the tail light in your Sierra 2500 HD. It is possible for the turn signal or brake light to work but the tailight part to be burnt out - replacing the bulb on your Sierra 2500 HD will restore functionality to both. Since the tailights are on whenever your parking lights or headlights are on, they will burn out eventually. Burn out tail lights are a common reason for a police officer to pull you over, so we recommend changing all of the tail lights on your Sierra 2500 HD whenever one is burnt out.
When changing the tailight bulb on your Sierra 2500 HD, be careful not to touch the glass part of the new bulb as this will cause the tailight bulb to burn out quicker.

本视频演示如何更换您 2009 GMC Sierra 2500 HD 车辆的烧坏的尾灯灯泡。 尾灯也称为后位灯或运行灯。 尾灯组中的部分灯泡，例如制动灯或转向灯，也可能同时作为您 Sierra 2500 HD 的尾灯使用。 转向灯或刹车灯可以正常工作，但尾灯部分烧坏——更换您 Sierra 2500 HD 的灯泡即可恢复转向灯和尾灯的正常使用。 由于尾灯在开启示宽灯或大灯时会一直亮着，最终会导致尾灯灯泡烧坏。 尾灯烧坏是警察拦截车辆的常见原因，因此我们建议一旦发现尾灯损坏，就立即更换您的 Sierra 2500 HD 上所有的尾灯。
在更换 Sierra 2500 HD 的尾灯灯泡时，务必不要触碰新灯泡的玻璃部分，否则会导致尾灯灯泡寿命缩短。
