Additional Notes

The 9003 bulb is a dual-filament halogen type with a P43t base, rated at 12V with 60W on high beam and 55W on low beam. Its single housing serves both beam functions, which is why the Saab 900 (1994-1998) shares the same bulb size across both high and low beam positions.
The 9004 bulb is also a dual-filament halogen type, but it uses a P29t base and carries a higher wattage split of 65W on high beam and 45W on low beam. This base type differs from the 9003 and the two are not interchangeable, despite both being dual-filament halogen bulbs.
The H6054 is a 5x7-inch rectangular sealed beam unit rather than a replaceable bulb. The entire lens, reflector, and filament assembly form one sealed unit, meaning the whole component is replaced rather than just an internal bulb. This format was used on the Saab 900 from 1981-1986.
The 1979-1980 Saab 900 used different sealed beam units for high and low beams. The H5001, a 4-inch square sealed beam, handled high beam duties, while the H5006, a 5.75-inch round sealed beam, was used for low beam. These two units are physically distinct and not interchangeable with each other.
All sealed beam types listed, including the H6054, H5001, and H5006, operate at 12V and conform to ANSI standards applicable in the United States and Canada. Like the halogen bulb types, they are not cross-compatible with one another due to differences in physical form and mounting.
The 9003 and 9004 bulbs share the same dual-filament halogen technology but differ in base type, wattage output, and physical connector design. Substituting one for the other is not supported by the specifications, as each corresponds to a distinct socket configuration in the vehicle.
