Additional Notes

All three bulb types specified for the Dodge D400 license plate position across the 1978-1980 model years follow the ANSI standard recognized in both the United States and Canada.
Each of the three bulb types uses a BA15s bayonet base, meaning all three share the same single-contact base configuration and are physically compatible with the same socket type.
Despite sharing the same BA15s base, the three bulbs operate at notably different wattages: the 1155 at 21W, the 97 at 13W, and the 67 at 8W, all at a nominal 12V.
The 1155 and 97 are both described as variants of the 1156 bulb, while the 67 is described as a lower wattage variant of the 1156, placing all three within the same broad 1156 family.
Because the 1155, 97, and 67 share a BA15s base, physical fitment across sockets is possible, but the significant wattage differences mean substitution between them would alter the electrical load and light output at the license plate position.
The 1980 Dodge D400 uses the 1155 bulb, which at 21W is the highest wattage specification across the three model years listed.
The 1979 Dodge D400 uses the 67 bulb, which at 8W is the lowest wattage specification across the three model years listed.
All three bulbs are single-filament types, consistent with a license plate illumination function that requires only a steady-on light with no high or low beam switching.
