The Saab 9-7x headlight bulb size specifications include a 9005 bulb for high beam operation and D1S or H11 bulbs for low beam operation. The replacement chart covers vehicle production years from 2005 to 2009 with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saab 9-7x uses the 9005 bulb for the high beam headlight across all model years from 2005-2009. This bulb follows the ANSI standard used in the US and Canada, operates at 12V and 65W, and features a single filament with a P20d base.
The low beam headlight position on the 9-7x accommodates two distinct bulb types depending on the headlamp system installed, and this split applies uniformly across all model years from 2005-2009.
Vehicles equipped with HID headlamps use the D1S bulb for the low beam. The D1S is a high-intensity discharge xenon bulb that operates at 85V and 35W, uses a PK32d-2 base, and includes an integral ignitor. It is designed specifically for projector-type housings and follows the ECE standard used in Europe and worldwide.
Vehicles equipped with halogen capsule headlamps use the H11 bulb for the low beam. The H11 is a single-filament halogen bulb operating at 12V and 55W with a PGJ19-2 base. It follows the ECE standard and is also approved for use in the US.
The D1S and H11 are not interchangeable. The D1S requires a projector-type housing and a high-voltage discharge circuit, while the H11 is a conventional low-voltage halogen bulb. Installing the wrong type for the headlamp system present on a given vehicle would result in an incompatible fit or non-functional lighting.
The 9005 and H11 bulbs share a 12V operating voltage but differ in wattage, base type, and socket configuration. The 9005 uses a P20d base at 65W, while the H11 uses a PGJ19-2 base at 55W, making them physically and electrically non-interchangeable despite both being halogen bulbs.
The D1S operates at a significantly higher voltage than the halogen bulbs in the same vehicle. At 85V, it requires dedicated ballast hardware that is part of the HID headlamp system and is absent in halogen-equipped variants of the 9-7x.
