Additional Notes

The Jeep Comanche uses two distinct bulb types for the license plate position across its production run: the 67 and the 194.
The 194 bulb is a miniature wedge type, classified under the T10 form factor, operating at 12 volts and drawing 3.78 watts. It fits the Jeep Comanche for model years 1986-1990.
The 67 bulb operates at 12 volts and draws 8 watts, making it a notably higher-wattage unit than the 194. It fits the 1991-1992 model years.
Both bulb types conform to ANSI standards recognized in the United States and Canada.
The 67 bulb uses a BA15s bayonet base, a single-contact base type that locks into its socket with a twist. The 194 uses a wedge base, which is retained by friction rather than a locking mechanism.
The 67 is a single-filament bulb, meaning it serves only one lighting function, consistent with its use in a license plate application.
The 67 bulb is described as a lower-wattage variant of the 1156. While the two share the BA15s bayonet base, the 1156 operates at a higher wattage, and the two are not interchangeable without accounting for that difference.
The base type change between the 194 wedge and the 67 bayonet means the bulbs are physically incompatible with each other's sockets, and substitution between the two types is not possible without a socket adapter.
