Additional Notes

The Simca 1204 uses the 97 bulb for its license plate position across the 1969-1971 model years.
The 97 is an ANSI-standardized bulb type recognized in the US and Canadian markets, operating at 12 volts and 13 watts.
It is a single-filament bulb, meaning it serves one lighting function rather than combining two, such as stop and tail, within a single unit.
The 97 uses a BA15s bayonet base, which is a single-contact bayonet mount that locks into its socket with a quarter-turn motion.
The 97 is a variant of the 1156 bulb type, though the two are not identical and direct substitution without confirming wattage and base pin alignment is not advised.
