Improve the appearance and nighttime driving visibility of your 1999-2006 GMC Sierra 1500 just by replacing your old weathered, worn out, and yellowing factory headlights with a brand new pair of Axial Headlights that feature black housings and clear lenses. With an impressive LED Daytime Running Light (DRL) design, these Headlights will give your Sierra 1500 a whole new look. Manufactured from OEM grade materials, these Headlights are assembled to precise standards for long-lasting quality. These Headlights feature durable, black ABS plastic housings with multi-faceted chromed reflectors, clear polycarbonate lenses, and modern LED lighting. Each housing is weather-sealed to prevent dirt and moisture from harming the state of the art electronics found inside. These Headlights were designed to be a direct plug and play replacement for your vehicle’s original factory housings. The DRL light bar portion of the headlight will require splicing into your running lights for operation. Please be sure to have your headlights properly aimed/aligned before driving at night.
