Additional Notes

The Saturn SC2 license plate bulb specification splits across two distinct bulb types depending on the model year, with the 168 bulb used from 1997-2002 and the 24 bulb used from 1993-1996.
The 168 bulb is a T10 miniature wedge type, meaning it uses a wedge-shaped base rather than a metal pin or bayonet fitting, and is rated at 12V and 4.9W.
The 24 bulb uses a BA9s base, which is a single-pin bayonet fitting with a 9mm cap, and operates at a lower 12V, 2W rating compared to the 168.
Both bulb types conform to ANSI standards recognized in the United States and Canada, placing them within a standardized North American automotive lighting classification system.
The two bulb types are not interchangeable. The 168 uses a wedge base while the 24 uses a BA9s bayonet base, meaning the socket design differs between the two production periods of the Saturn SC2.
The wattage difference between the two bulbs is notable. The 168 draws 4.9W while the 24 draws 2W, reflecting a meaningful difference in power consumption for the license plate lighting circuit.
The T10 designation of the 168 bulb refers to a tubular glass envelope roughly 10/8 of an inch wide, a standard sizing convention used in ANSI bulb classification.
