GMC Acadia Headlight Bulb Size

GMC Acadia headlight bulbs utilize 9012, D3S, and D1S sizes for both high beam and low beam applications, with bulb specifications varying across model generations. The replacement chart covers 2007 through 2019 production years and details corresponding bulb size specifications for each generation.

Additional Notes

The GMC Acadia uses four distinct bulb types across its headlight specifications: 9012, D3S, D1S, H7, and H11. The halogen types (9012, H7, and H11) all operate at 12V and 55W, while the HID types (D3S and D1S) operate at 35W but differ significantly in ignition voltage, with D1S requiring 85V and D3S requiring 42V.
The 9012 is a single-filament enhanced halogen bulb with a PX22d base, built to ANSI standards for the US and Canadian markets. On the GMC Acadia (2013-2019), it serves as the specified halogen option for both high beam and low beam positions.
The D3S is a mercury-free HID xenon discharge bulb with a PK32d-5 base and an integral ignitor, designed for projector-type housings. It follows ECE standards and is specified for both high beam and low beam positions on halogen and HID-equipped Acadia models from 2013-2019.
The D1S is an HID xenon discharge bulb with a PK32d-2 base and an integral ignitor, also intended for projector-type housings. It is specified for both high beam and low beam positions on HID-equipped Acadia models from 2007-2012.
The H7 and H11 are separate halogen bulbs used on the 2007-2012 Acadia with halogen capsule headlamps. The H7, which carries a PX26d base, is specified for the high beam position, while the H11, which carries a PGJ19-2 base, is specified for the low beam position. These two bulbs are not interchangeable with each other due to their different base types.
The D1S and D3S bulbs share the same 35W power rating but use different base types, PK32d-2 and PK32d-5 respectively, making them physically incompatible with each other. Substituting one for the other is not supported by the fitment data.
The 9012 bulb, while functionally related to the 9006 family, is not directly interchangeable with standard 9006 bulbs due to its enhanced output design and PX22d base configuration. Its use on the Acadia is specific to halogen capsule headlamp assemblies from 2013-2019.
On the 2007-2012 Acadia, the halogen and HID configurations require entirely different bulb sets. Halogen-equipped models use H7 and H11, while HID-equipped models use D1S for both beam positions, reflecting a complete change in the lighting system rather than a simple bulb substitution.
