Additional Notes

The Dodge Monaco license plate bulb specifications cover model years 1965-1978 and 1990-1992, with three distinct bulb types used across that span: the 168, 97, and 67.
The 168 is the most frequently specified bulb across the Monaco's license plate fitment data, appearing in nine of the sixteen model years listed.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, conforming to ANSI standards for the US and Canadian markets. Its wedge base design requires no separate socket retainer, as the bulb body itself acts as the retention mechanism.
The 97 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 13W. It is described as a variant of the 1156, though it draws considerably more wattage than the 168 used in other Monaco model years.
The 67 shares the same BA15s bayonet base as the 97 and is also a single-filament bulb, but is rated at a lower 8W. It is described as a lower wattage variant of the 1156.
Because the 97 and 67 share the same BA15s bayonet base type, their sockets are physically similar, though their wattage ratings differ. Substituting one for the other would result in a mismatch in power draw relative to the original specification.
The 168 wedge base and the BA15s bayonet base used by the 97 and 67 are mechanically incompatible socket types, meaning bulbs from these two groups are not interchangeable regardless of voltage rating.
The Dodge Monaco (1965-1967) used the 67 bulb for the license plate position, while the 1990-1992 Monaco used the 168, reflecting a change in base type across the model's production history.
All three bulb types listed are rated at 12V, consistent with the standard 12-volt electrical systems used in passenger vehicles across the model years covered.
The 97 bulb, at 13W, draws notably more power than both the 67 at 8W and the 168 at 4.9W, which is relevant when considering socket and wiring load tolerances in the original lamp housing.
