Additional Notes

The Ford Country Squire license plate bulb specifications span from 1950 to 1991, with six distinct bulb types used across that period: the 168, 194, 90, 97, 1155, 67, and 63.
The 168 and 194 are both T10 miniature wedge bulbs operating at 12V, differing only in wattage at 4.9W and 3.78W respectively. The Ford Country Squire used the 168 from 1988-1991 and the 194 solely in 1987, making these two the most recently specified types in the data.
The T10 wedge base format used by both the 168 and 194 is a tool-free push-in fitment, which differs fundamentally from the bayonet-base construction found in the bulb types specified for earlier model years.
The 97, 1155, and 67 are all single-filament bulbs sharing the BA15s bayonet base and are each described as variants of the 1156. Despite this shared base, their wattages differ substantially: 13W for the 97, 21W for the 1155, and 8W for the 67. This means the base type alone does not confirm interchangeability.
The Ford Country Squire used the 1155 from 1963-1967, which at 21W is the highest-wattage bulb in the entire specification set. Its elevated wattage relative to other BA15s variants in this data indicates it draws significantly more current than the 97 or 67.
The 67 bulb was specified for the Ford Country Squire from 1956-1962. At 8W, it is the lowest-wattage BA15s bayonet bulb in these specifications, and substituting a higher-wattage BA15s variant such as the 1155 would not be electrically equivalent despite the shared base fitting.
The 97 was specified from 1968-1972 and shares both its BA15s base and its 13W rating with the 90 bulb used in 1973-1974. However, the 97 is described as a variant of the 1156 while the 90 carries no such designation, indicating a distinction in their design or application classification.
The 63 bulb, specified for the Ford Country Squire from 1950-1955, uses a BA9s base rather than the BA15s base found on the 90, 97, 1155, and 67. The BA9s is a smaller bayonet fitting, making the 63 physically incompatible with sockets designed for any of the BA15s-based bulbs in this specification set.
At 0.63W, the 63 bulb operates at a fraction of the power drawn by any other bulb type in these specifications. This places it in a distinctly different electrical category from all other bulbs listed.
All bulb types across the full specification range are ANSI standards applicable to both the US and Canada, operating at 12V nominal voltage.
