Ford Ranch Wagon Map Light Bulb Size

The Ford Ranch Wagon map light utilizes bulb sizes 63, 67, 89, 631, 214-2, and 1003 depending on the specific version of the vehicle. Available data for the components covers the range from 1953 to 1974.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Ford Ranch Wagon map light draws from six distinct bulb types across its model years: the 1003, 214-2, 631, 89, 67, and 63.
The 1003 is the most frequently specified bulb in the Ford Ranch Wagon map light fitment data, covering the 1962-1966 and 1974 model years. It is a single-filament, 12V, 21W bulb with a BA15s bayonet base, built to ANSI standards for the US and Canadian markets.
The 631 shares the same BA15s bayonet base, voltage, and wattage rating as the 1003 and is classified as a variant of the 1156. It serves the 1967-1970 model years in this application.
Although the 1003 and 631 share identical electrical ratings at 12V and 21W with the same BA15s base, they carry separate ANSI designations and are listed as distinct part numbers in the specifications.
The 214-2 is the sole festoon-style bulb in the dataset. At 41mm in length with an SV8.5 base, its physical form differs substantially from the bayonet-base bulbs used in all other listed years. It is rated at 12V and 12W and applies to the 1973 Ford Ranch Wagon.
The 89 bulb, specified for the 1959-1960 model years, uses the same BA15s bayonet base as the 1003 and 631 but operates at a lower wattage of 13W. It is described as a lower wattage variant of the 1156.
The 67 bulb, covering the 1956-1957 model years, also carries a BA15s bayonet base and is rated at 12V and 8W, making it the lowest-wattage bayonet-base bulb in this set of specifications.
The 63 bulb, specified for the 1953-1955 model years, is the only bulb in the dataset with a BA9s base rather than a BA15s base. Its rating of 12V and 0.63W places it in a significantly lower power class than all other bulbs listed.
The BA9s base of the 63 bulb is physically incompatible with the BA15s base used by the 1003, 631, 89, and 67 bulbs, meaning these types are not interchangeable despite sharing the same operating voltage.
All six bulb types in the specifications conform to ANSI standards applicable to the US and Canadian markets.
