How to Replace the Headlight Bulbs in a GMC Sierra?

Model: GMC Sierra MK 4 - Years 2014-2018
Part: Headlight bulb

In this tutorial, you will see how to replace the headlight bulbs in a GMC Sierra, a very simple operation. For the passenger side headlight, you must first remove the air filter box because the available space is really tight. To do this, simply remove all the mounting bolts with a 8mm socket wrench, disconnect the intake duct, and remove the base. At this point, you can remove the plastic panel located at the back of the headlight, open the large cap, and proceed with replacing the bulb by turning it counterclockwise to extract it from the housing.
