Additional Notes

The bulb size 67 is an ANSI-standardized type used in both the United States and Canada, operating at 12 volts and 8 watts.
The 67 bulb uses a BA15s bayonet base, which is a single-contact fitting with a 15mm base width and two offset pins that lock the bulb in place upon a quarter-turn rotation.
As a single-filament bulb, the 67 type serves one lighting function only, which in this context is license plate illumination.
The 67 bulb is a lower wattage variant of the 1156, meaning the two types share the BA15s base but are not interchangeable due to the difference in wattage and light output.
The Dodge Suburban uses the 67 bulb for the license plate position across the 1957-1958 model years.
