Additional Notes

The GMC Jimmy license plate bulb specifications cover model years 1973 through 2001, with three distinct bulb types used across that span: the 194, the 67, and the 97.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards for the US and Canadian markets. Its wedge base design requires no separate socket retainer, as the bulb body itself locks into the housing.
The GMC Jimmy uses the 194 bulb for its license plate light in model years 1992-1997 and 2001.
The 67 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 8W. It is a lower-wattage variant within the 1156 bulb family and also conforms to ANSI standards for the US and Canadian markets.
The Jimmy uses the 67 bulb for license plate illumination across model years 1979-1991, making it the bulb type associated with the longest continuous span in these specifications.
The 97 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 13W. It is also a variant of the 1156 family and meets the same ANSI standards as the 67.
The 97 bulb is specified for the Jimmy in model years 1973-1978.
Although the 67 and 97 share the same BA15s bayonet base, their wattage ratings differ significantly, at 8W and 13W respectively. This difference means the two bulb types are not interchangeable without accounting for the electrical load variation.
The 194 wedge base is physically incompatible with the BA15s bayonet socket used by the 67 and 97, so no cross-substitution is possible between the 194 and either of the other two types without a socket adapter.
The 67 and 97 share the BA15s bayonet base form factor with the widely available 1156, though wattage differences within that family make direct substitution a matter of matching the specified wattage rather than base type alone.
