Additional Notes

The Dodge W100 license plate bulb specifications cover model years 1975-1977 and 1984-1989, with four distinct bulb types used across those years: 168, 1155, 67, and 97.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W, conforming to ANSI standards for the US and Canadian markets. Its wedge base design requires no locking mechanism, as the bulb is held in place by tension from the socket itself.
The 168 bulb is specified for the Dodge W100 in model years 1984, 1988, and 1989, making it the most frequently appearing bulb type across the listed specifications.
The 1155 bulb uses a BA15s single-contact bayonet base and is rated at 12V and 21W. It is described as a variant of the more widely known 1156 bulb, sharing the same base type but differing in electrical output.
The 1155 is specified for model years 1985 and 1987. At 21W, it operates at a notably higher wattage than the other bulb types listed for this vehicle's license plate position.
The 67 bulb also uses a BA15s bayonet base and is rated at 12V and 8W. It is described as a lower wattage variant of the 1156 and is specified solely for the 1986 model year.
The 97 bulb shares the BA15s bayonet base with both the 1155 and 67 bulbs and is rated at 12V and 13W. It is specified for model years 1975-1977.
Although the 1155, 67, and 97 bulbs all share the BA15s bayonet base, their wattage ratings differ at 21W, 8W, and 13W respectively. This distinction means they are not interchangeable without accounting for differences in electrical load.
The T10 wedge base of the 168 bulb is physically incompatible with the BA15s bayonet sockets used by the 1155, 67, and 97 bulbs, making cross-substitution between these two base types impossible without socket modification.
All four bulb types conform to ANSI standards applicable in both the United States and Canada, indicating they are designed for North American automotive electrical systems operating at 12V.
