Subaru GL License Plate Bulb Size

The Subaru GL license plate light requires bulb sizes 194, 67, or 89 depending on the specific vehicle configuration. Available information covers the time range from 1975 to 1989.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Subaru GL uses three distinct bulb types across its model years for the license plate position: the 194, 67, and 89, 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 the GL's license plate specifications.
The Subaru GL (1982-1989) uses the 194 bulb for the license plate position, representing the most widely specified bulb across the model's documented years.
Within the 1985-1989 range, the 194 bulb is specified exclusively for vehicles equipped with halogen capsule headlamps, indicating a trim or package dependency for those years.
The 1982-1984 entries also call for the 194 bulb but carry no headlamp condition, meaning the fitment applies regardless of headlamp type in those years.
The 67 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 8W, and is specified for the 1980-1981 model years.
The 89 bulb shares the same BA15s bayonet base as the 67 but operates at a higher wattage of 13W, and it is specified solely for the 1975 model year.
Both the 67 and 89 bulbs are described as lower-wattage variants of the 1156, meaning they share the same BA15s base but are not electrically interchangeable with it due to wattage differences.
The 67 and 89 bulbs use a bayonet-style base, while the 194 uses a wedge-style base, meaning these bulb families are physically incompatible with one another regardless of voltage rating.
Across the full span of documented years, the GL transitioned through three different base types for the license plate bulb, from the BA15s bayonet in earlier years to the T10 wedge in later ones.
