Additional Notes

The Subaru GLF uses two distinct bulb types across its model years for the license plate position: the 194 and the 67, both conforming to ANSI standards recognized in the United States and Canada.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W. Its wedge base design means it is held in place by tension from the socket itself rather than by a locking mechanism.
The 67 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 8W. The BA15s designation indicates a single-contact bayonet fitting with a 15mm base width.
The 67 is described as a lower wattage variant of the 1156 bulb. While the two share the same BA15s bayonet base, they are not the same bulb, and substituting a 1156 in place of a 67 would introduce a higher wattage draw to the circuit.
The 194 and the 67 use fundamentally different base types, a wedge base versus a bayonet base, making them physically non-interchangeable with each other.
The 1982 Subaru GLF takes the 194 bulb for the license plate position, while the 1980-1981 model years take the 67 bulb, reflecting a change in socket type between those production periods.
At 3.78W, the 194 draws notably less power than the 8W 67 bulb. This difference is relevant when considering replacement options, as the socket and wiring for each year are matched to their respective wattage ratings.
