Additional Notes

All three bulb types specified for the Mercury Park Lane license plate position, the 97, 1155, and 67, are ANSI standards recognized in both the United States and Canada.
Each of these three bulb types shares the same BA15s bayonet base, a single-contact base design where the bulb locks into the socket with a twist.
All three types operate at 12 volts, consistent with standard automotive electrical systems of the era.
The 97, 1155, and 67 are each single-filament bulbs, meaning they produce only one level of light output with no dual-function capability.
All three bulb types are variants of the 1156, differing primarily in wattage output.
The 1155 bulb, rated at 21 watts, is the highest-wattage option among the three and was specified for the Mercury Park Lane across the 1964-1967 model years.
The 97 bulb, rated at 13 watts, was specified for the 1968 Mercury Park Lane, representing a reduction in wattage compared to the 1155 used in prior years.
The 67 bulb, rated at 8 watts, is the lowest-wattage variant among the three and was specified for the 1958-1960 Mercury Park Lane.
Because the 97, 1155, and 67 all share the BA15s bayonet base, physical fitment across model years is mechanically possible, though wattage differences mean they are not electrically interchangeable without consideration of circuit compatibility.
