Saturn SC1 high beam headlight bulbs use 9005 size while low beam headlight bulbs use 9006XS or 9006 size. The replacement chart covers vehicle production years from 1993 to 2002 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saturn SC1 uses the 9005 bulb for the high beam headlight across all model years from 1993-2002. This bulb is an ANSI-standard single-filament halogen type operating at 12V and 65W, fitted with a P20d base.
The 9006 bulb serves as the low beam headlight for the Saturn SC1 from 1993-2000. It is also an ANSI-standard single-filament halogen bulb, operating at 12V and 55W, but carries a P22d base rather than the P20d base found on the 9005.
The low beam specification shifts from the 9006 to the 9006XS for the 2001-2002 model years. The 9006XS is a variant of the 9006 with a straight 180-degree base configuration, while retaining the same 12V and 55W electrical ratings.
Because the 9006 and 9006XS share identical voltage and wattage ratings but differ in base geometry, the two bulbs are not directly interchangeable despite their electrical similarity. The straight 180-degree base of the 9006XS is physically distinct from the P22d base of the standard 9006.
The 9005 high beam bulb draws 65W, while both low beam variants, the 9006 and 9006XS, draw 55W. This 10W difference reflects the typical halogen design practice of allocating higher wattage to high beam applications for greater light output at distance.
All three bulb types specified for the SC1 conform to ANSI standards recognized in both the United States and Canada, indicating a standardized North American fitment profile across the entire production range.
