Additional Notes

The Plymouth Cuda uses two distinct bulb sizes for the license plate position across the 1970-1974 model years, specifically the 97 and the 67.
Both the 97 and 67 are ANSI-standardized bulbs recognized in the United States and Canada, and both feature a BA15s single-contact bayonet base with a single filament.
The BA15s bayonet base uses a twist-and-lock mounting style with a single contact pin, which distinguishes it from the dual-pin BA15d base used in twin-filament applications.
The 97 bulb operates at 12 volts and 13 watts, while the 67 bulb operates at 12 volts but at a lower 8 watts, making the two electrically incompatible as direct substitutes despite sharing the same base type.
Both bulbs are described as variants of the 1156, meaning they share the same BA15s base but differ in wattage output from that reference bulb.
The Plymouth Cuda (1972-1974) takes the 97 bulb for the license plate position, while the 1970-1971 model years require the lower-wattage 67 bulb.
Because the 97 and 67 share the same BA15s base, one would physically fit the socket of the other, but the wattage difference means substituting one for the other falls outside the factory specification.
