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
This video shows you how to change the highbeams, which are also known as brights or headlight high beam bulbs, in your 2021 Chevrolet Silverado 3500 HD. High beam lights can also be commonly referred to as a full beam whereas your headlights may be called the low beams. The high beam symbol in the dashboard on a 2021 Chevrolet Silverado 3500 HD is typically represented as a blue headlight icon with beams pointing outward. In some Chevrolets your headlight and high beams are the same bulb – it is possible for the headlight portion of the bulb to burn out and for the highbeams to continue to function properly and vice versa. Replacing the bulb will restore functionality to both high and low beam functions. Highbeam bulbs grow dimmer by over 20% over time, therefore we recommend changing both bulbs on your Silverado 3500 HD at the same time, even if only one is burnt out - this will allow both high beam bulbs to have the same brightness on each side.
Be careful not to touch the glass part of the new highbeam bulb with your finger when changing it on your Silverado 3500 HD. Touching the new highbeam bulb will cause the bulb to burn out quicker. If you accidentally touch the glass part, wipe it off with rubbing alcohol before inserting it into your Silverado 3500 HD.

本视频演示如何更换您的 2021 雪佛兰 Silverado 3500 HD 车辆的远光灯，远光灯也称为明亮灯或大灯远光灯灯泡。 远光灯也可以称为全光束，而你的前大灯可能被称为近光灯。 在一台 2021 年款的 雪佛兰 Silverado 3500 HD 车辆仪表盘上，远光灯符号通常表现为一个蓝色大灯图标，灯束向外延伸。 在某些 雪佛兰车型 车辆上，前大灯和远光灯共用同一个灯泡——有可能是大灯部分的灯泡烧坏，而远光灯仍能正常工作，反之亦然。 更换灯泡将恢复远光灯和近光灯的功能。 远光灯灯泡的亮度会随时间降低超过 20%。因此，即使只烧坏一侧，也建议同时更换 Silverado 3500 HD 的两侧灯泡，以保持左右远光灯亮度一致。
更换Silverado 3500 HD上的远光灯泡时，务必不要用手指触碰新灯泡的玻璃部分。 触摸新的远光灯泡会导致灯泡烧坏速度加快。 如果意外接触到玻璃部分，请先用酒精擦拭干净，再将其插入您的 Silverado 3500 HD 中。
