Additional Notes

The Saturn SL2 license plate bulb specifications cover the 1991-2002 model years, with two distinct bulb types used across that span.
The 168 bulb is an ANSI-standard miniature wedge type with a T10 base, rated at 12 volts and 4.9 watts, and it fits the Saturn SL2 for model years 1996-2002.
The T10 wedge base on the 168 bulb is a push-in design that requires no separate socket locking mechanism, making it one of the most widely used bases in automotive lighting applications.
The 24 bulb is an ANSI-standard single-filament type with a BA9s bayonet base, rated at 12 volts and 2 watts, and it fits the 1991-1995 model years.
The BA9s base on the 24 bulb uses a pin-and-twist retention method, which is physically and mechanically incompatible with the T10 wedge socket used in later model years.
The 168 and 24 bulbs are not interchangeable. Their base types, wattage ratings, and socket designs are all different, meaning a bulb from one fitment group cannot be installed in a socket designed for the other.
Both bulb types are recognized under ANSI standards applicable in the United States and Canada, placing them within a standardized classification system used across multiple vehicle manufacturers.
The 168 bulb draws 4.9 watts compared to the 2 watts of the 24 bulb, reflecting a meaningful difference in power consumption between the two fitment groups.
