Additional Notes

All three bulb types specified for the Dodge D450 across 1978-1980 share the BA15s bayonet base, a single-contact base design where a single pin aligns the bulb within its socket.
All three bulbs operate at 12 volts, consistent with the standard electrical system voltage found in automotive applications of that era.
The 1155, 67, and 97 are all ANSI-standardized bulbs recognized in both the United States and Canada, meaning they conform to a defined set of electrical and physical parameters.
Each of the three bulbs carries a single-filament design, which is typical for non-switching lighting functions such as license plate illumination.
The 1155, specified for the 1980 model year, is rated at 21 watts, making it the highest-wattage bulb among the three years listed.
The 67, specified for the 1979 model year, is rated at 8 watts and is described as a lower-wattage variant of the 1156 bulb family.
The 97, specified for the 1978 model year, is rated at 13 watts, placing it between the 67 and 1155 in terms of power consumption.
Although the 1155, 67, and 97 all share the BA15s bayonet base, their differing wattage ratings indicate they are not interchangeable without accounting for the electrical load differences each places on the circuit.
All three bulbs are described as variants of the 1156, a widely used automotive bulb, though each differs from the 1156 in wattage output.
