The Saab 9-2X headlight bulb specifications include a 9005 size for high beam operation and D2R or H1 sizes for low beam operation. The replacement chart covers 2005 to 2006 model years 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 9-2X uses the 9005 bulb for the high beam headlight across both the 2005-2006 model years. This is a single-filament halogen bulb rated at 12V and 65W, built to the ANSI standard used in the United States and Canada, and it seats in a P20d base.
The low beam headlight on the 2005-2006 Saab 9-2X varies by headlamp system. Vehicles fitted with halogen capsule headlamps use the H1 bulb, while those fitted with HID headlamps use the D2R bulb. These two bulb types are not interchangeable with each other.
The H1 is a single-filament halogen bulb rated at 12V and 55W. It uses a P14.5s base and is built to the ECE standard, though it also carries approval for use in the United States and Japan.
The D2R is a high-intensity discharge bulb that operates on xenon gas. It runs at 85V and 35W and requires an external ignitor to strike and sustain the arc. Its P32d-3 base and the "R" designation in its name indicate it is specifically designed for reflector-type headlamp housings, making it incompatible with projector-type housings that call for the D2S variant.
The 9005 and H1 bulbs share a 12V operating voltage but differ in wattage, base type, and governing standard. Substituting one for the other is not supported by the specifications, as each position in the headlamp assembly is designed around a specific bulb type.
