Additional Notes

The Chevrolet One-Fifty Series uses two distinct bulb types across its 1953-1957 model years for the license plate position: the 67 and the 63.
The 67 bulb is an ANSI-standardized type recognized in both the United States and Canada, operating at 12 volts and 8 watts with a single filament.
It uses a BA15s bayonet base, which is a single-contact bayonet fitting, and is classified as a lower wattage variant of the more widely known 1156 bulb.
The 63 bulb is also an ANSI-standardized type for the US and Canadian markets, though it operates at a significantly lower output of 12 volts and 0.63 watts with a single filament.
The 63 uses a BA9s base, a miniature single-contact bayonet fitting that is physically incompatible with the BA15s base of the 67, making the two bulbs non-interchangeable.
The Chevrolet One-Fifty Series (1955-1957) takes the 67 bulb in the license plate position.
The 1953-1954 model years require the 63 bulb, reflecting a different socket specification from the later models.
