Additional Notes

The Saturn SW1 uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across all model years from 1993-1999, making both bulb types consistent throughout the vehicle's entire production run in these specifications.
Both the 9005 and 9006 are single-filament halogen bulbs operating on a 12-volt system, which is standard for automotive electrical systems of this type.
The 9005 high beam bulb carries a 65W rating, while the 9006 low beam bulb is rated at 55W. The lower wattage of the low beam reflects its design for sustained use without generating excess heat toward oncoming traffic.
The 9005 uses a P20d base and the 9006 uses a P22d base. These two base types are physically distinct, meaning the high beam and low beam bulbs are not interchangeable despite their otherwise similar construction.
Both bulb types conform to ANSI standards recognized in the United States and Canada, indicating they meet a defined set of performance and dimensional requirements for the North American market.
The single-filament design of both bulbs means each serves only one lighting function, which is why the Saturn SW1 requires separate bulbs for high and low beam operation rather than a dual-filament unit handling both.
