Install LED Bulbs in the Fog Lights on the GMC Sierra

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

Before starting the replacement of the fog light bulbs on the GMC Sierra, position your vehicle on a lift or a stable, secure surface. Take this precaution to ensure the operator's safety. This should be done whenever performing maintenance on a vehicle. Now, once you locate the bulb position at the back of the bumper, remove the bulb from its housing and disconnect the electrical power. Replace the old bulb with the new LED bulb and reinsert it into its socket. Repeat the same process for the fog light on the other side. And that's it!
