Additional Notes

The Chevrolet C-Series Pickup uses three distinct bulb types across its license plate lighting specifications: the 194, 67, and 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.
The 194 bulb is the most widely specified type for the Chevrolet C-Series Pickup, covering model years 1988-2000.
The 67 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 8W, and is described as a lower wattage variant of the 1156 bulb type.
The 67 bulb is specified for model years 1981-1986.
The 97 shares the same BA15s bayonet base as the 67 but operates at a higher wattage of 13W, making it a distinct variant of the 1156 type rather than a direct substitute for the 67.
The 97 bulb is specified for model years 1975-1979.
The T10 wedge base of the 194 and the BA15s bayonet base of the 67 and 97 are physically incompatible mounting types, meaning bulbs from one group are not interchangeable with those from the other.
Although the 67 and 97 share the same BA15s bayonet base, their wattage ratings differ at 8W and 13W respectively, and they are not listed as interchangeable within these specifications.
All three bulb types conform to ANSI standards applicable in both the United States and Canada.
