Saturn SW2 headlights use 9005 bulb size for high beam and 9006 bulb size for low beam applications. The replacement chart covers 1993 to 2001 model years 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 SW2 uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across all model years from 1993-2001.
Both the 9005 and 9006 are ANSI-standardized halogen bulb types recognized in the United States and Canada, meaning they conform to a defined set of electrical and physical specifications rather than being proprietary to any single manufacturer.
The 9005 is a single-filament halogen bulb rated at 12 volts and 65 watts, fitted with a P20d base, and serves the high beam function across the entire SW2 production run.
The 9006 is a single-filament halogen bulb rated at 12 volts and 55 watts, fitted with a P22d base, and handles the low beam function across the same 1993-2001 span.
Although the 9005 and 9006 share the same voltage rating and a visually similar form, their base types differ: the P20d base on the 9005 and the P22d base on the 9006 are not interchangeable, as each base is keyed to its respective socket configuration.
The 10-watt difference between the 9005 and 9006 reflects their intended roles, with the higher-wattage 9005 producing greater light output suited to high beam distances and the lower-wattage 9006 optimized for the controlled, downward-directed pattern of a low beam.
