Additional Notes

The Jeep Grand Wagoneer uses two distinct bulb types across its license plate lighting specifications: the 168 and the 67.
The 67 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 8W, and is classified as a lower wattage variant of the 1156 bulb under the ANSI standard applicable in both the US and Canada.
The 168 bulb is a miniature wedge type in a T10 form factor, rated at 12V and 4.9W, and also carries ANSI standard designation for the US and Canadian markets.
The BA15s bayonet base of the 67 bulb and the wedge base of the 168 bulb are physically incompatible with each other, meaning the two bulb types are not interchangeable.
The 67 bulb is specified for the Jeep Grand Wagoneer license plate position across the 1984-1991 model years, with the exception of 1992.
The 168 bulb is specified for the 1993 Grand Wagoneer license plate position, representing a different base type and lower wattage than the 67 used in prior years.
At 4.9W, the 168 draws notably less power than the 8W 67 bulb, a relevant consideration when evaluating socket and wiring compatibility between model years.
