Additional Notes

The Jeep FC150 uses two distinct bulb types across its model years for the license plate position: the 89 and the 63, each with different base types and wattage ratings.
The 89 bulb follows the ANSI standard applicable in the US and Canada. It is a single-filament bulb with a BA15s bayonet base, rated at 12V and 13W, and is considered a lower wattage variant of the 1156 bulb.
The 63 bulb also follows the ANSI standard for the US and Canada. It is a single-filament bulb with a BA9s base, rated at 12V and 0.63W, making it significantly lower in wattage than the 89.
The BA15s base on the 89 and the BA9s base on the 63 are physically incompatible with each other, meaning the two bulb types are not interchangeable despite both being single-filament designs.
The 1966 Jeep FC150 uses the 89 bulb for the license plate position, while the 1957 model uses the 63 bulb, reflecting a difference in socket fitment between the two years.
