Additional Notes

The Chrysler Windsor uses two distinct bulb types across its 1950-1961 model years for the license plate position: the 63 and the 67.
The bulb 67 is an ANSI-standard single-filament bulb 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 63 is an ANSI-standard single-filament bulb rated at 12V and 0.63W, fitted with a BA9s base, making it considerably lower in wattage than the 67.
The BA15s and BA9s bases are physically incompatible with each other, meaning bulbs from the two groups are not interchangeable despite both being single-filament 12V types.
The Chrysler Windsor (1956-1961) takes the 67 bulb for the license plate position.
The 63 bulb applies to the 1950-1955 model years for the same position.
The transition between bulb types occurred between the 1955 and 1956 model years, representing a shift from the BA9s-based 63 to the BA15s-based 67.
Both the 63 and 67 bulbs carry ANSI designations valid in both the United States and Canada, indicating standardized specifications across North American markets.
