For the 2016 GMC Acadia, the low- and high-beam bulb depend on the factory headlight system. Models with halogen headlights use a 9012 bulb for both low beam and high beam. Models equipped with HID headlights use a D3S bulb for both functions. Confirm the headlight type before ordering, since 9012 and D3S applications are not interchangeable.
Additional exterior lighting varies by location and includes the following listed fitments:
- Fog lights: H11 LED or H16 LED
- Front turn signal and parking light: 7444NA
- Front side marker: 194NA
- Reverse light: 921
- Brake, center stop, daytime running, tail, rear turn signal, rear side marker, and license plate lights: LED
Interior applications include 212-2 for the dome light, 168 or 917 for map lights, 921 for the trunk light, 6612F for the vanity light, and 2721 for the auto light.
