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 reverse light in a car is typically called the "reverse lamp" or "backup light". It is a white light located at the rear of the vehicle, and it illuminates when the car is shifted into reverse gear, to provide visibility to the driver when backing up. This how-to video shows you how to change a burnt out reverse light bulb in your 1991 GMC C1500. These bulbs burn out occasionally and get dimmer over time. We suggest replacing the reverse light bulbs in your 1991 C1500 in pairs.
Try not to touch the glass part of the new bulb with your finger when changing the reverse light in your C1500, the oil in your finger will cause that part of the reverse light bulb to burn hotter out therefore burn out quicker. Using gloves or a piece of paper towel will limit the potential of touching the bulb.

汽车上的倒车灯通常称为"倒车灯"或"倒车灯"。 这是一个位于车辆后部的白色灯，当车辆挂入倒挡时会点亮，用于在倒车时为驾驶员提供可视性。 本操作视频将指导您如何更换您的 1991 GMC C1500 车辆中烧坏的倒车灯灯泡。 这些灯泡偶尔会烧坏，随着时间推移会变暗。 我们建议成对更换您 1991 C1500 车辆的倒车灯灯泡。
更换C1500的倒车灯时，不要用手指触碰新灯泡的玻璃部分，手指上的油会使得倒车灯泡该部分温度升高，从而导致灯泡更早烧毁。 使用手套或纸巾巾可以减少触碰灯泡的可能性。
