Additional Notes

The 67 bulb is the sole license plate bulb type listed for the Chevrolet Nomad across all model years covered by these specifications, spanning 1955-1961.
The 67 bulb follows the ANSI standard, meaning it conforms to a recognized North American specification used across both the United States and Canada.
It is a single-filament bulb, indicating it serves one lighting function rather than combining two, such as stop and tail duties.
The 67 bulb uses a BA15s bayonet base, which is a single-contact bayonet mount with a 15mm collar width, requiring a socket designed for that specific base type.
The bulb operates at 12 volts and draws 8 watts, placing it in the lower output range of the BA15s bayonet family.
The 67 is described as a lower wattage variant of the 1156 bulb, which shares the BA15s bayonet base but operates at a higher wattage, meaning the two are not interchangeable despite the physical similarity of their bases.
