Source note on shared footage
We have a massive and growing video library, but we don't have everything...yet.
Car companies often use the same engines in different cars. They also slightly alter the styling and sell the same car by two different names (amongst other tricks to help offset development costs).
Our system selects the most applicable video for your car based, in part, on these characteristics. The video displayed may not look exactly like your car, but may be relevant enough for you to get a good idea how to do it.

我们有一个庞大且不断增长的视频资料库，但还没有全部内容……
汽车制造商经常在不同车型中使用相同的发动机。 它们还略微调整了外观设计，并以两个不同的名称销售同一款车（以及其他一些技巧，以帮助抵消开发成本）。
我们的系统会根据这些特性，部分地选择最适合您车辆的视频。 视频中显示的内容可能与您的车辆外观不完全相同，但可能足够相关，让您了解如何操作。
Procedure notes
The video above shows you how to change a burnt out front turn signal bulb on your 2020 GMC Sierra 2500 HD. If the turn signal (also known as a blinker or flasher) blinks rapidly or doesn't blink at all / stays stuck when engaged, this is your Sierra 2500 HD's way of telling you that a turn signal bulb is burnt out. Troubleshooting for burnt out turn signal bulbs in your Sierra 2500 HD is relatively easy - turn your hazard lights on and check the front of your Sierra 2500 HD and then the back, whichever side is not illuminating is the side with the burnt out bulb. We recommend that you change both the driver and passenger side bulbs at the same time as they get dimmer over time and if one is out, then the other one is likely to burn out soon.When changing the turn signal bulb in your Sierra 2500 HD, be careful not to touch the glass portion of the bulb with your fingers as this will cause the bulb to burn out prematurely.
