Ford Falcon License Plate Bulb Size

Additional Notes

• All three bulb types specified for the Ford Falcon license plate position across the 1960-1970 model years share the same BA15s bayonet base, meaning the physical mounting interface is identical across the entire production span covered by these specifications.
• Each bulb type listed is an ANSI-standardized part recognized in both the United States and Canada, placing them within a widely adopted North American automotive lighting standard.
• The bulb 67, fitted to the Ford Falcon for 1960-1962, operates at 8 watts, making it the lowest-wattage option among the three types specified.
• The bulb 1155, used for 1963-1966, operates at 21 watts, the highest wattage of the three types in these specifications, drawing notably more current than the 67 or 97 despite sharing the same base type.
• The bulb 97, specified for 1967-1970, operates at 13 watts, placing it between the 67 and 1155 in terms of power consumption.
• All three bulb types are described as single-filament designs, which is typical for license plate lighting, where no switching between brightness levels is required.
• Each of the three bulb types is identified as a variant of the 1156, a common BA15s single-filament reference bulb. Because wattage differs across the 97, 1155, and 67, substituting one for another would alter current draw even though the base fits all three sockets.
• The shared BA15s base across all specified years does not indicate interchangeability, since the wattage differences among the 67, 97, and 1155 mean that a replacement must match the wattage specified for the relevant model year rather than relying solely on physical fitment.
• All bulbs in these specifications operate on a 12-volt system, consistent with the 12V electrical architecture standard in North American passenger vehicles of this era.
