The Saab 9-3 headlight bulb size chart specifies high beam and low beam bulb sizes including D1S, H7, 9003, H11, and D2S for the headlight assembly. The replacement chart covers vehicle production years from 1999 to 2011 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 9-3 uses five distinct bulb types across its headlight specifications: D1S, D2S, H7, H11, and 9003. The H7 is the most frequently listed type, appearing across both high beam and low beam positions for multiple model years.
The 9003 bulb is an ANSI-standard dual-filament halogen type rated at 12V with a 60W high beam filament and a 55W low beam filament. Its dual-filament design means a single bulb serves both beam functions, which is reflected in the 1999-2002 specifications where the same 9003 size is listed for both the high beam and low beam positions.
The H7 and H11 are both single-filament ECE-standard halogen bulbs rated at 12V, 55W, but they use different bases. The H7 uses a PX26d base, while the H11 uses a PGJ19-2 base. These two types are not interchangeable despite sharing the same voltage and wattage ratings.
The D1S and D2S are both ECE-standard HID xenon discharge bulbs operating at 85V, 35W, designed for projector-type housings. A key distinction between them is that the D1S has an integral ignitor built into the bulb, whereas the D2S requires a separate external ignitor. This makes the two types physically and electrically incompatible with each other.
For the 2008-2011 Saab 9-3, the high beam headlight position accepts either a D1S or an H7 bulb depending on whether the vehicle was equipped with HID or halogen capsule headlamps. These are separate headlamp system configurations, not interchangeable bulb options within the same housing.
The low beam headlight on the 2004-2007 Saab 9-3 used D2S for HID-equipped vehicles, while the 2008-2011 model years shifted to D1S for the same HID low beam position. The two xenon bulb generations are not interchangeable due to the differing ignitor configurations.
For 2007 Saab 9-3 models, the high beam uses only the H7 regardless of headlamp type, while the low beam varies between D2S and H7 depending on the headlamp system. This means HID-equipped 2007 vehicles use different bulb types for high and low beam functions.
The 9003 bulb carries a P43t base and conforms to ANSI standards used in the US and Canada, while all other bulb types listed in these specifications conform to ECE standards used in Europe and worldwide. The H7 and H11 also carry US approval, but the 9003 is the only ANSI-native type in the specifications.
