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 replace a headlight bulb in your 2015 Chevrolet Express 3500, your headlight bulb may also be known as a headlight low beam. Headlights grow dimmer by up to 20% over time and eventually burn out - for this reason, we recommend changing your headlights in pairs. Changing both headlight bulbs on your Express 3500 at the same time will allow both bulbs to have the same intensity and prevent the new headlight bulb from appearing brighter than the bulb on the opposite side.
In some Chevrolets, the highbeam is the same bulb as the headlight and it is possible for the highbeam to work, but the headlight be burnt out even if they are the same bulb (and vice versa). Some Chevrolets have high intensity discharge headlights, sometimes referred to as xenon lights. Xenon headlights have a ballast to ignite the high voltage xenon lights when they turn on that can remain energized even if the lights are turned off. Be sure to disconnect the headlight assembly or battery before attempting to replace it. If your Express 3500 has a HID headlight burnt out, it could be a burnt out bulb or failed headlight ballast.
The headlight bulb replacement cost for your Express 3500 varies depending on where you go to get your headlight replaced. Chevrolet dealerships will tend to be pricier and parts retailers such as AutoZone will often replace it for free if you buy bulbs there. When you change the headlight on your Express 3500, it is important to not touch the glass part of the bulb with your fingers because the oil from your fingertips will cause that part of the bulb to burn hotter, which significantly shortens the life of the bulb.

本视频演示如何更换您的 2015 雪佛兰 Express 3500 车辆的前大灯灯泡，您的前大灯灯泡也可能被称为近光灯。 前大灯随时间推移亮度会逐渐变暗，最多可能降低 20%，最终会烧坏 - 因此，我们建议您成对更换前大灯。 同时更换您的 Express 3500 的两个前大灯灯泡，可以使两个灯泡亮度相同，避免新更换的灯泡比对侧的灯泡显得更亮。
在一些 雪佛兰车型 车型中，远光灯和大灯共用同一个灯泡，可能出现远光灯正常工作而大灯烧坏的情况（反之亦然）。
一些 雪佛兰车型 车辆配备了高强度放电头灯，有时也称为氙气灯。 氙气大灯具有一个镇流器，用于在开启时点燃高压氙气灯，即使灯关闭，镇流器仍可能保持通电状态。 更换前，请务必断开大灯总成或蓄电池。 如果您的 Express 3500 车型的 HID 头灯烧坏，可能是灯泡烧坏或头灯镇流器故障。
你的 Express 3500 车头灯灯泡更换费用因你选择哪家地方进行头灯更换而异。 雪佛兰 经销商的收费通常较高；AutoZone 等配件零售商往往会为在店内购买灯泡的顾客免费更换。 在更换 Express 3500 的大灯时，切勿用手指触摸灯泡的玻璃部分，因为指尖的油会使得灯泡该部分温度升高，从而显著缩短灯泡的使用寿命。
