Additional Notes

The Ford Sunliner map light specifications span model years 1953 through 1960, covering three distinct bulb types across that range.
The bulb 63 is an ANSI-standardized single-filament type rated at 12V and 0.63W, fitted with a BA9s miniature bayonet base. It is the lowest-wattage bulb in these specifications.
The Ford Sunliner (1953-1955) uses the 63 bulb for the map light position.
The bulb 67 is an ANSI-standardized single-filament type rated at 12V and 8W, fitted with a BA15s bayonet base. It is described as a lower-wattage variant of the 1156 bulb.
The 1956-1957 model years use the 67 bulb, representing a significant wattage increase over the 63 bulb used in earlier years.
The bulb 89 is an ANSI-standardized single-filament type rated at 12V and 13W, also fitted with a BA15s bayonet base, and is likewise a lower-wattage variant of the 1156 bulb.
The 1959-1960 model years use the 89 bulb for the map light position.
The 67 and 89 bulbs share the same BA15s bayonet base, but their wattage ratings differ at 8W and 13W respectively, which means they are not interchangeable without affecting light output.
The 63 bulb uses a BA9s base, which is physically incompatible with the BA15s base found on both the 67 and 89 bulbs, making cross-substitution between the earlier and later model years impossible without modification.
All three bulb types in these specifications are ANSI-standardized and rated for 12V electrical systems, consistent with the 12-volt automotive standard that became widespread in the mid-1950s.
