Additional Notes

The 1968-1969 Buick GS 350 uses the 97 bulb for the license plate position.
The 97 is an ANSI-standardized bulb recognized in both the United States and Canada.
It operates on a 12-volt system and draws 13 watts.
The 97 uses a BA15s bayonet base, which is a single-contact base that locks into its socket with a twist.
The bulb carries a single filament, meaning it serves one lighting function rather than switching between two brightness levels.
The 97 is a variant of the 1156 bulb type, though the two are not necessarily interchangeable due to differences in wattage and other electrical characteristics.
