Additional Notes

The Saturn SC1 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 it operates at 12V with a 4.9W output.
The 24 bulb uses a BA9s base, which is a single-pin bayonet cap with a 9mm cap body, and it operates at 12V with a 2W output, drawing notably less power than the 168.
Both bulb types conform to ANSI standards applicable in the US and Canada, placing them within a standardized sizing and performance 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 designs are physically incompatible with one another.
The Saturn SC1 (1997-2002) requires the 168 bulb, which at 4.9W produces a higher light output than the 2W 24 bulb specified for the 1993-1996 model years.
The BA9s base on the 24 bulb is among the smaller bayonet cap formats in automotive use, reflecting the low-power, compact nature of that bulb's application in license plate illumination.
The T10 wedge format of the 168 bulb is one of the most widely used miniature bulb configurations in automotive lighting, which contributes to broad aftermarket availability for 1997-2002 SC1 applications.
