Additional Notes

The bulb size 67 is an ANSI-standardized type recognized across 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 where the pin is centered on the base, distinguishing it from dual-contact bayonet variants.
The 67 bulb is a single-filament type, meaning it serves one lighting function rather than switching between two brightness levels as dual-filament bulbs do.
The 67 bulb is a lower wattage variant of the 1156, sharing the same BA15s base but drawing less power, which makes the two types physically similar yet not electrically identical.
The White WHM license plate bulb specification for 1984-1987 and 1981 calls for the 67 bulb size, applying this across all listed model years.
Each listed year for the White WHM carries an "Except Conventional" qualifier, indicating the 67 bulb fitment applies only to non-conventional configurations of the vehicle.
