Additional Notes

The Citroen D Special (1970-1972) uses the 97 bulb for its license plate lighting.
The 97 is an ANSI-standardized bulb type recognized across the United States and Canada.
It operates on a 12-volt electrical system and draws 13 watts, placing it in the low-wattage range typical of auxiliary lighting applications.
The 97 uses a BA15s bayonet base, which is a single-contact fitting that locks into its socket with a twist.
As a single-filament bulb, the 97 serves only one lighting function, unlike dual-filament types used in combined stop and tail applications.
The 97 is a variant of the 1156, meaning the two share the same BA15s base design, though they are not identical and substitution between them requires verification of voltage and wattage tolerances before use.
