Additional Notes

The Fiat 124 license plate bulb specifications cover model years 1976-1983, with two distinct bulb sizes used across that span.
The bulb 67 is an ANSI-standardized single-filament type rated at 12V and 8W, fitted with a BA15s bayonet base, and is classified as a lower wattage variant of the 1156 bulb.
The bulb 97 shares the same BA15s bayonet base and 12V operating voltage as the 67 but draws more current at 13W, making it a higher-output variant of the 1156 family.
Both the 67 and 97 conform to ANSI standards recognized in the United States and Canada.
The Fiat 124 uses the 67 bulb for license plate illumination across model years 1979-1983.
Model years 1976-1978 of the Fiat 124 use the 97 bulb instead, which operates at a notably higher wattage than the 67 used in later years.
Although both bulbs share the BA15s bayonet base, the wattage difference between the 67 and 97 means they are not direct interchangeable replacements without accounting for the power draw variation.
The BA15s base designation indicates a single-contact bayonet fitting with a 15mm base width, a common format in automotive lighting applications.
