Additional Notes

The bulb size 63 is an ANSI-standard single-filament bulb rated at 12 volts and 0.63 watts, fitted with a BA9s base, which is a miniature bayonet cap commonly used in low-current indicator and license plate applications.
The Jeep 6-226 uses the size 63 bulb for the license plate position across the 1956-1957 model years.
The BA9s base type is not interchangeable with other common miniature bases such as the wedge (W2.1x9.5d) or the festoon, so fitment requires a bulb that specifically matches the BA9s pin configuration.
