Subaru Standard License Plate Bulb Size

The Subaru Standard license plate light uses bulb sizes 194, 89, and 67 depending on the specific production period. Available data covers the time range from 1979 through 1987.

Additional Notes

The Subaru Standard uses three distinct bulb types across its license plate fitments: the 194, 89, and 67, all of which conform to ANSI standards applicable in the United States and Canada.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, making it one of the lowest-wattage bulbs in these specifications. It was used on the Subaru Standard for model years 1984-1987.
The 89 bulb uses a BA15s single-contact bayonet base and is rated at 12V and 13W. It is described as a lower-wattage variant of the 1156 bulb, which itself is a widely used automotive single-filament type.
The 67 bulb also uses a BA15s bayonet base and is similarly described as a lower-wattage variant of the 1156, though it is rated at a lower 8W compared to the 89's 13W.
Because the 89 and 67 share the same BA15s bayonet base, their physical mounting interface is identical, yet their wattage ratings differ. Substituting one for the other without accounting for the wattage difference would result in an incorrect power draw for the circuit.
The 194's wedge-style base is physically incompatible with the BA15s bayonet socket used by the 89 and 67, meaning these bulb types are not interchangeable across different model years of the Subaru Standard.
Model years 1981-1982 and 1979 each used different bulb types despite falling within a close production window, with 1981-1980 specifying the 67 and 1979 and 1982-1983 specifying the 89.
