Fog Light Replacement 2007 GMC Sierra 2500 HD Classic SL 6.6L V8 Turbo Diesel Extended Cab Pickup (4 Door)

The video above shows how to change the fog light bulb in your 2007 GMC Sierra 2500 HD. Not all models have fog lights - for many GMCs, it depends on your trim level (Classic SL) or whether the fog light option was ordered when your Sierra 2500 HD 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 2500 HD, 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 2500 HD, be careful not touch the glass part of the bulb with your fingers which causes the bulb to burn out earlier.
