Additional Notes

The Oldsmobile Super 88 license plate bulb specifications cover model years 1951 through 1964.
Three distinct bulb types appear across these model years: the 63, the 67, and the 1155, all of which conform to ANSI standards recognized in the United States and Canada.
The 67 bulb is the most frequently specified type, serving the Oldsmobile Super 88 from 1953 through 1963.
The 67 is a single-filament bulb rated at 12V and 8W, fitted with a BA15s bayonet base, and is classified as a lower wattage variant of the 1156 bulb.
For the 1964 model year, the Oldsmobile Super 88 uses the 1155 bulb rather than the 67, representing a change in the license plate bulb specification for that year.
The 1155 is also a single-filament bulb with a BA15s bayonet base and is rated at 12V and 21W, making it significantly higher in wattage than the 67 despite sharing the same base type and being a variant of the 1156.
Although the 67 and 1155 share the BA15s bayonet base, their wattage ratings differ substantially at 8W and 21W respectively, which is a relevant fitment consideration when sourcing replacements.
The 1951-1952 model years use the 63 bulb, which carries a BA9s base rather than the BA15s found on the 67 and 1155, making it physically incompatible with sockets designed for those later bulb types.
The 63 is rated at 12V and 0.63W, placing it in a much lower output category than either the 67 or the 1155.
The base type change from BA9s on the 63 to BA15s on the 67 marks a socket-level difference between the 1952 and 1953 model years, meaning bulbs from those two generations are not interchangeable.
