Additional Notes

The Dodge Coronet license plate bulb specifications span model years 1950 through 1976, covering four distinct ANSI-standard bulb types across that period.
The bulb 67 is the most widely used type across the Coronet's license plate fitment history, appearing in model years 1956-1969 as well as 1965-1969, and is a single-filament bulb with a BA15s bayonet base rated at 12V and 8W.
The bulb 63, used on the Dodge Coronet from 1950-1955, operates at 12V but draws only 0.63W, making it the lowest-wattage bulb in these specifications. It uses a BA9s base, which is physically smaller than the BA15s base found on bulbs 97 and 67.
The bulb 168 is a T10 miniature wedge type, meaning it uses no base pins or bayonet fittings and instead relies on the wedge shape of its glass envelope to make electrical contact. It is rated at 12V and 4.9W, and it fits the 1974-1976 Coronet.
The bulb 97, used on the 1972-1973 Coronet, shares the BA15s bayonet base with bulb 67 but draws significantly more power at 13W versus 8W. Despite the shared base type, the two are not interchangeable due to the wattage difference, which affects brightness and socket load.
The BA15s bayonet base found on bulbs 67 and 97 is a single-contact design, consistent with single-filament applications such as license plate illumination.
The transition from bulb 63 to bulb 67 between the 1955 and 1956 model years represents a base type change from BA9s to BA15s, meaning sockets from those two generations are not physically compatible with each other.
The transition to bulb 168 for the 1974-1976 model years marks a shift from bayonet-base construction to a wedge-base format, indicating a socket design change that is incompatible with the BA15s-based bulbs used in prior years.
