Additional Notes

The 1958 Edsel Corsair uses a type 67 bulb for the license plate position, while the 1959 model year uses a type 89 bulb. Both are ANSI-standardized types recognized in the United States and Canada.
The type 67 and type 89 bulbs share the same BA15s bayonet base, which is a single-contact base with a 15mm barrel. Despite this shared base, the two bulbs are not the same wattage and are not direct substitutes for one another.
The type 67 operates at 12 volts and draws 8 watts, while the type 89 operates at 12 volts and draws 13 watts. The higher wattage of the type 89 means it produces more heat and light output than the type 67.
Both bulb types are described as lower wattage variants of the 1156 bulb. The 1156 is a widely used automotive single-filament bulb that shares the BA15s base, which explains the physical compatibility across these three types.
Because the 1958 and 1959 Corsair use different bulb types despite the shared base design, substituting a type 89 into a 1958 application or a type 67 into a 1959 application would result in a wattage mismatch with the original specification.
