Additional Notes

The BA15s bayonet base is the sole base type across all license plate bulb positions in the Dodge W300 specifications, appearing in every model year from 1975 through 1980.
All three bulb types listed, the 1155, 67, and 97, are ANSI-standardized single-filament bulbs rated at 12 volts, making them compatible with standard 12V automotive electrical systems.
The 97 bulb is specified for the Dodge W300 across four consecutive model years, 1975-1978, making it the most frequently recurring bulb type in these specifications.
Although the 1155, 67, and 97 bulbs share the same BA15s bayonet base, their wattage ratings differ significantly: the 1155 draws 21W, the 97 draws 13W, and the 67 draws 8W.
The 1155 and 97 are both described as variants of the 1156 bulb. Despite sharing a base type and voltage rating, their wattage values differ, which means they are not direct substitutes for one another without accounting for brightness and circuit load differences.
The 1980 Dodge W300 uses the 1155 bulb, which at 21W is the highest-wattage license plate bulb in the entire specification set.
The 67 bulb, specified for the 1979 model year, is the lowest-wattage option in these specifications at 8W, drawing notably less power than the 1155 used the following year.
Because the 1155, 67, and 97 are all variants of the 1156 family with a shared BA15s base, physical fitment into the socket is possible across types, but substituting one for another would alter the light output and electrical load at the license plate position.
