How to Change the Low Beam Bulb on a GMC Sierra

Model: GMC Sierra MK 3 - Years 2007-2014
Part: Headlight bulb

To change the low beam bulb on a GMC Sierra, first remove the airbox by unscrewing the 4 screws using a T20 Torx wrench. At the back of the headlight, remove the cover to access the low beam bulb. Take out the bulb holder by turning it counterclockwise. Disconnect the bulb by releasing the tabs, ensuring the connector does not fall off. Take the new bulb out of the package and insert it into the bulb holder. Screw the bulb holder with the bulb back into its housing and test the bulb to see if it works. Now, replace the headlight cover and reattach the airbox, securing the lower clips and tightening the Torx screws.
