Additional Notes

The Ford Ranch Wagon license plate bulb specifications span from 1950 to 1974, with six distinct bulb types used across that period: the 90, 97, 1155, 67, and 63.
The bulb 67 is the most frequently specified type in the Ford Ranch Wagon license plate position, covering the 1956-1962 model years. It 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.
The bulb 63 is specified for the 1950-1955 model years. Unlike all other bulb types in these specifications, it uses a BA9s base rather than a BA15s bayonet base, and operates at a notably low 0.63W on a 12V circuit.
The BA9s base on the 63 bulb is physically incompatible with the BA15s base used by every other bulb type in these specifications. The two base types are not interchangeable.
The bulb 1155 is specified for the 1963-1967 model years. It is an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V and 21W, and is a variant of the 1156.
At 21W, the 1155 draws significantly more power than the other BA15s-based bulbs in these specifications, which range from 8W to 13W. Substituting a different BA15s bulb in place of the 1155 would result in a wattage mismatch.
The bulb 97 is specified for the 1968-1972 model years. It shares the BA15s bayonet base and 12V, 13W rating with the 90 bulb, and is also described as a variant of the 1156.
The bulb 90 is specified for the 1973-1974 model years. It carries the same BA15s base, 12V supply, and 13W rating as the 97, though the two are listed as separate ANSI part numbers and are not described as interchangeable in these specifications.
The bulbs 90, 97, 1155, and 67 all share the BA15s bayonet base, meaning the socket interface is physically consistent across the 1956-1974 model years, even though wattage varies between those types.
All five bulb types in these specifications conform to ANSI standards recognized in both the United States and Canada.
