Additional Notes

The bulb size 63 is an ANSI-standardized type used in the United States and Canada, operating at 12 volts with a power draw of 0.63 watts.
The 63 bulb uses a BA9s base, a miniature single-contact bayonet fitting commonly associated with low-wattage indicator and license plate applications.
The Dodge B-3 uses the 63 bulb for the license plate position across the 1951-1952 model years.
As a single-filament bulb, the 63 type serves a fixed, non-switchable lighting function with no secondary filament for reduced-intensity operation.
The BA9s base of the 63 bulb is not interchangeable with wedge-base or festoon-type bulbs, which require different socket designs.
