Ford Galaxie 500 License Plate Bulb Size

The Ford Galaxie 500 license plate component utilizes unique bulb sizes 90, 97, 1155, and 67 depending on the specific production version. Available data covers the range from 1962 through 1974 for the specified vehicle lighting equipment.

Additional Notes

The Ford Galaxie 500 license plate bulbs span four distinct ANSI bulb types across the 1962-1974 model years: the 90, 97, 1155, and 67.
All four bulb types share the same BA15s single-contact bayonet base and operate on a 12-volt system, which reflects a consistent electrical architecture across the entire production range covered by these specifications.
The BA15s base is a single-contact bayonet fitting, meaning the bulb seats and locks with a push-and-twist motion and carries current through one contact point at the base.
All four bulb types are single-filament designs, which is typical for license plate lighting since the application requires only a steady-on function with no dimming or dual-intensity operation.
The 1155 bulb, fitted to the Ford Galaxie 500 for the 1963-1967 model years, draws 21 watts, making it the highest-wattage bulb among the four types listed and notably more power-intensive than the others in this application.
The 67 bulb, used on the 1962 model, draws only 8 watts, the lowest wattage of any bulb type in these specifications.
The 97 and 1155 bulbs are each described as variants of the 1156, a widely used automotive bulb. Despite sharing that relationship and the same base type, they differ in wattage: the 97 draws 13W while the 1155 draws 21W, making them non-interchangeable without accounting for that power difference.
The 90 bulb, used on the 1973-1974 models, shares the same 12V and 13W rating as the 97 but is not described as a variant of the 1156, indicating a distinct part classification despite the matching electrical values.
Because the 97 and 90 bulbs share identical voltage and wattage ratings and the same BA15s base, their physical and electrical compatibility warrants verification before any substitution is made, as ANSI classifications can reflect differences beyond electrical ratings alone.
The bulb type changed three times across the 1962-1974 span of the Galaxie 500, with transitions occurring after the 1962, 1967, and 1972 model years, meaning a replacement bulb must correspond to the specific model year rather than the nameplate as a whole.
