Saturn SL2 high beam headlight bulbs use 9005 size while low beam headlight bulbs use 9006 size. The replacement chart covers vehicle production spanning 1991 to 2002.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saturn SL2 uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across all model years from 1991-2002.
Both the 9005 and 9006 are single-filament halogen bulbs operating on a 12-volt system, meaning each bulb handles only one lighting function rather than combining high and low beam output in a single unit.
The 9005 is rated at 65 watts, while the 9006 draws 55 watts, reflecting the typically higher output demanded of high beam applications compared to low beam.
The 9005 uses a P20d base and the 9006 uses a P22d base, making the two bulbs physically non-interchangeable despite their otherwise similar construction and voltage rating.
Both bulb types conform to ANSI standards recognized in the United States and Canada, classifying them within a standardized North American automotive lighting system.
The P20d and P22d base designations refer to specific bayonet-style single-contact bases, where the numeric portion indicates the base width in millimeters, further distinguishing the two bulbs from one another.
