Description	Bulb Size
ANSI standard (US & Canada). Single-filament bulb with BA15s bayonet base. Lower wattage variant of 1156. 12V, 8W.	67

The bulb size 67 is the sole license plate bulb specified for the White WIL across the 1984-1987 model years.
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 operates on a 12-volt electrical system and draws 8 watts, placing it in the lower power range of the BA15s bayonet bulb family.
The 67 uses a BA15s bayonet base, which is a single-contact base type. This base design does not interchange with dual-contact bayonet bases such as the BA15d.
The 67 is described as a lower wattage variant of the 1156 bulb. Although both share the BA15s base, the difference in wattage means the two are not functionally identical and substitution between them warrants attention to the electrical load requirements of the socket.
