Additional Notes

The 67 bulb is the sole license plate bulb size listed for the American Motors Classic across all documented model years, spanning 1961-1966.
The 67 bulb follows the ANSI standard, meaning it conforms to a recognized North American specification shared across the United States and Canada.
It operates on a 12-volt electrical system at 8 watts, placing it in the low-wattage range typical of auxiliary lighting applications such as license plate illumination.
The 67 bulb uses a BA15s bayonet base, which is a single-contact bayonet mount. The "s" in BA15s denotes a single center contact, as opposed to the dual-contact BA15d variant.
The 67 is described as a lower wattage variant of the 1156 bulb. Both share the BA15s bayonet base, but the 1156 operates at a higher wattage, making the two bulbs physically interchangeable in base type while differing in output and electrical draw.
Because the 1156 draws more power than the 67, substituting a 1156 in a socket rated for the 67 may exceed the intended load for that circuit in the American Motors Classic.
