Additional Notes

The Plymouth Sapporo uses the ANSI 67 bulb for its license plate position across all documented model years, spanning 1978-1983.
The 67 bulb operates on a 12-volt electrical system and draws 8 watts, placing it in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The 67 bulb is a single-filament type, meaning it serves one lighting function only, with no secondary circuit for a dimming or braking mode.
It uses a BA15s bayonet base, which is a single-contact bayonet mount. The "s" designation indicates a single contact pin, as opposed to the offset dual-contact BA15d variant.
The 67 bulb conforms to ANSI standards recognized in both the United States and Canada, reflecting its use across North American vehicle applications.
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 similar yet electrically distinct and not directly interchangeable in all applications.
