Fog Light Replacement 2006 GMC Sierra 3500 WT 6.6L V8 Turbo Diesel Standard Cab Pickup (2 Door)

The video above shows how to change the fog light bulb in your 2006 GMC Sierra 3500. Not all models have fog lights - for many GMCs, it depends on your trim level (WT) or whether the fog light option was ordered when your Sierra 3500 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 Sierra 3500, 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 Sierra 3500, be careful not touch the glass part of the bulb with your fingers which causes the bulb to burn out earlier.
