Additional Notes

The Plymouth Conquest uses the ANSI 67 bulb for its license plate position across the 1984-1986 model years.
The 67 bulb operates on a 12-volt electrical system at 8 watts, placing it in the low-wattage range typical of non-critical 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 braking or running light combinations.
It is mounted via a BA15s bayonet base, which is a single-contact bayonet fitting. The "s" designation indicates a single contact point at the base, distinguishing it from the dual-contact BA15d variant.
The 67 bulb is recognized under ANSI standards applicable in both the United States and Canada, reflecting a shared North American standardization for this bulb type.
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 applications where wattage tolerance is a factor.
