Additional Notes

The bulb type 97 follows the ANSI standard applicable in the United States and Canada, making it a regionally standardized component rather than a proprietary specification.
The 97 bulb uses a BA15s bayonet base, which is a single-contact bayonet mount with a 15mm base collar and a single locating pin, distinguishing it from double-contact variants used in other applications.
As a single-filament bulb, the 97 type serves functions that require only one lighting mode, such as a steady-on license plate light, with no capacity for dual-intensity operation.
The 97 bulb operates at 12 volts and draws 13 watts, consistent with standard 12V automotive electrical systems.
The 97 is noted as a variant of the 1156 bulb. While both share the BA15s base, the two are not universally interchangeable, as differences in wattage or physical size between variants can affect fitment and circuit compatibility.
The Mazda Mizer used the 97 bulb size for its license plate light across the 1976-1977 model years.
