Procedure notes
The video above shows how to change the fog light bulb in your 2015 BMW M4. Not all models have fog lights - for many BMWs, it depends on your trim level (Base) or whether the fog light option was ordered when your M4 was manufactured. Fog lights are typically in the front bumper, below the headlight cluster and are helpful in poor visibility. If one fog light is burnt out on your M4, we recommend changing both bulbs because the working bulb will be dimmer than the one you replaced and will likely burn out soon anyway.
When you change the foglight on your M4, be careful not touch the glass part of the bulb with your fingers which causes the bulb to burn out earlier.

上方视频介绍如何更换 2015 年款 宝马 M4 的雾灯灯泡。 并非所有车型都配有雾灯。对于许多 宝马 车型，这取决于配置级别（Base），或者 M4 出厂时是否选装了雾灯。 雾灯通常位于前保险杠内、前照灯总成下方，可在能见度较低时提供帮助。 如果 M4 的一侧雾灯烧坏，原作者建议同时更换两侧灯泡，因为仍在工作的旧灯泡会比新灯泡暗，而且可能也即将损坏。
更换 M4 的雾灯时，请勿用手指触碰灯泡的玻璃部分，否则可能使灯泡提前损坏。
