Additional Notes

The bulb 1003 is the most frequently specified dome light bulb for the Ford Ranch Wagon, covering model years 1956-1969. It is an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V and 21W.
The bulb 63 is specified for the Ford Ranch Wagon from 1950-1955. It is an ANSI-standard single-filament bulb with a BA9s base, rated at 12V and 0.63W, making it the lowest-wattage dome bulb in these specifications.
The 1003 and 105 both use a BA15s bayonet base, but they are not interchangeable. The 1003 draws 21W while the 105 draws 13W, and substituting one for the other would alter the electrical load on the circuit.
The 105 bulb, specified for 1970-1971, is noted as a variant of the 1156. Despite sharing the BA15s bayonet base with the 1003, the wattage difference distinguishes it as a separate fitment requirement.
For 1972-1973, the Ranch Wagon uses the 561 festoon bulb, which is 44mm in length with end-cap contacts and is rated at 12V and 12W. This type of bulb makes contact at both ends rather than through a base socket.
The 211-2 festoon bulb, specified for 1974, uses an SV8.5 base rather than end-cap contacts. Although it shares the same 12V and 12W rating as the 561, the differing base type means the two festoon bulbs are not interchangeable.
The 63 bulb uses a BA9s base, which is physically smaller than the BA15s base found on the 1003 and 105. These base types are incompatible with one another.
All bulbs listed in these specifications conform to ANSI standards applicable in both the United States and Canada, indicating consistent regulatory classification across the full range of model years covered.
