Additional Notes

The Saturn SC uses the ANSI 24 bulb for its license plate light across the 1991-1992 model years.
The ANSI 24 is a single-filament bulb, meaning it serves one lighting function rather than combining multiple functions such as brake and tail into a single unit.
The bulb operates at 12 volts, which is consistent with standard automotive electrical systems.
At 2 watts, the ANSI 24 draws very little power, a characteristic typical of license plate bulbs given their purely illumination role under regulatory requirements.
The ANSI 24 uses a BA9s base, a miniature bayonet-style cap with a 9mm collar width, which determines physical socket compatibility.
The BA9s base is not interchangeable with other common automotive bases such as the wedge-type T10 or the bayonet-style BA15s, so substitutions require confirmation of base type before fitment.
