FOR 05-07 GMC SIERRA 1500 2500HD 3500 LEFT SIDE BUMPER FOG LIGHT LAMP GM2592154

Fog lights are usually a factory option, and provide great auxiliary lighting to complement the headlights. Fog lights are especially useful in adverse conditions such as rain, snow, and fog, when visibility is significantly reduced. Fog lights mount to factory predetermined areas on the bumper where they look the best and do not sacrifice aerodynamics.
