Additional Notes

The Subaru GL-10 license plate bulb specifications cover model years 1985-1989, all noted under the halogen capsule headlamp configuration.
Two bulb types appear across these model years: the 194 and the 67, both 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 lower-wattage bulbs in common automotive use.
The 67 uses a BA15s single-contact bayonet base and is rated at 12V and 8W, drawing more than twice the wattage of the 194.
The 67 is a lower-wattage variant of the 1156 bulb family, sharing the same BA15s base type but differing in power output, which means the two are not interchangeable despite the physical similarity.
The 194 and 67 use entirely different base types, a wedge mount versus a bayonet mount, so neither bulb is a physical substitute for the other.
The Subaru GL-10 (1986-1987 and 1989) takes the 194 bulb for the license plate position, while the 1985 and 1988 model years take the 67.
Because the bulb type alternates between model years rather than following a single continuous specification, the production year must be confirmed before selecting a replacement.
