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 center brake light on your 1990 GMC Safari, which is sometimes referred to as the third brake light or stoplight is also known as the center high mount stop lamp (CHMSL). The 3rd brake lights up when you hit the brake pedal and helps prevent you from being rear ended by the cars behind you. See how to change the center brake light (CBL) on your GMC Safari in this how-to video. Be careful not to touch the bulb directly with your fingers when you replace the center brake light bulb on your Safari, touching the bulb causes the it to burn out quicker.
A burnt out center brake light bulb in your Safari is an excuse for a police officer to pull you over. Check your bulbs frequently and change burnt bulbs promptly. Sometimes the stoplight has multiple bulbs in the housing whereas in other vehicles, the 3rd brake light is an LED brake light strip that must be replaced all at once.

你的 1990 GMC Safari 车的中间制动灯，有时也被称为第三制动灯或停车灯，也称为中间高位刹车灯（CHMSL）。
踩刹车时，3rd刹车灯亮起，有助于防止后方车辆追尾。 参见本操作视频，了解如何更换您的 GMC Safari 的中央制动灯（CBL）。
更换Safari车辆中央制动灯灯泡时，务必避免手指直接接触灯泡，否则会导致灯泡烧坏速度加快。
你的Safari中控刹车灯泡烧坏，是交警拦车的理由。 经常检查灯泡，一旦发现烧坏立即更换。 有时停车灯罩内包含多个灯泡，而在其他车辆中，3rd制动灯是LED制动灯条，必须整体更换。
