Procedure notes
This how-to video shows you how to change the parking light bulb in your 2009 Mercedes-Benz GL450. The parking lights on a car are also known as position lights or clearance lights. The parking light symbol in the 2009 Mercedes-Benz GL450 dashboard is represented by two small semi-circles facing opposite directions. The parking light is typically orange in color and the parking light bulb may be the same bulb as the turn signal bulb in some GL450s. It is possible for the turn signal filament of the dual function parking light and turn signal bulb to burn out and for the parking light to continue to function properly. Replacing the parking light bulb will restore functionality of both your turn signal and parking light in your GL450.
When changing the parking light in your GL450, be careful not to touch the glass part of the new bulb with your finger as this will cause it to burn out quicker. We recommend using gloves or a piece of paper towel to limit the potential of touching the bulb.

本操作视频演示了如何更换您的 2009 奔驰 GL450 车辆的示宽灯灯泡。 汽车的示宽灯也称为位置灯或照明灯。 在 2009 奔驰 GL450 车辆的仪表盘上，示宽灯符号由两个朝相反方向的小半圆表示。 示宽灯通常为橙色，某些 GL450s 中，示宽灯灯泡可能与转向灯灯泡为同一灯泡。双功能示宽灯和转向灯灯泡的转向灯灯丝可能会烧坏，而示宽灯仍能正常工作。 更换示宽灯灯泡将恢复您GL450车辆转向灯和示宽灯的正常功能。
在更换您 GL450 的示宽灯时，务必避免用手指触摸新灯泡的玻璃部分，否则会导致灯泡寿命缩短。 我们建议使用手套或纸巾来避免触摸灯泡。
