Headlight Assembly Set w/ DRL

These assemblies feature a complete set of headlights and parking/turn signal lights for both the driver and passenger sides. These headlights incorporate advanced lighting features, including bright white Daytime Running Lights (DRLs) that enhance your vehicle's visibility during the day. When signaling a turn, the DRLs seamlessly switch to amber signal lights, providing a clear indication to other drivers and offering a unique custom lighting effect. Compatibility is specific to the 2001 GMC Sierra C3, 2002-2006 GMC Sierra 1500 Denali, 2007 GMC Sierra 1500 Denali Classic, and 2001-2006 GMC Yukon Denali and Yukon XL 1500 Denali models. Please note that bulbs are not included, and you will reuse your original bulbs. The low beam uses a 9006 bulb, and a 9005 bulb is used for the high beam; notching of the bulb base may be required to fit into the 9005 bulb plug.
