For the 2008 GMC Acadia, the high-beam application is D1S. The low beam is listed as either D1S or H11, so confirm the bulb currently installed and the specific headlamp configuration before ordering. These options should not be treated as interchangeable without checking the vehicle’s headlight assembly.
