Additional Notes

The license plate bulb for the Oldsmobile 98 is the 194 across the 1979-1996 model years, with the sole exception of 1978, which uses the 168. Both the 194 and 168 are T10 miniature wedge bulbs operating at 12V, though they differ in wattage: the 194 draws 3.78W while the 168 draws 4.9W. These two types share the same wedge base form factor but are not rated identically, so substituting one for the other affects the wattage load on the circuit.
The 1965-1973 model years use the 97 bulb, a single-filament type with a BA15s bayonet base rated at 12V and 13W. The 97 is classified as a variant of the 1156 family, meaning it shares the same base style but carries different electrical characteristics than the standard 1156.
The 1964 model year stands alone in the specifications with the 1155 bulb, also a BA15s single-filament type and a variant of the 1156 family, but rated at a notably higher 21W. This makes the 1155 the highest-wattage license plate bulb across the entire range covered by these specifications.
The 1953-1963 model years use the 67 bulb, another BA15s single-filament type rated at 12V and 8W. Like the 97 and 1155, the 67 is described as a lower-wattage variant of the 1156 family. Despite sharing the same base type as the 97 and 1155, the 67 operates at a lower wattage than both, and the three are not interchangeable without accounting for those differences.
The 1950-1952 model years use the 63 bulb, which differs from all other bulbs in these specifications by using a BA9s base rather than a BA15s or wedge base. Rated at 12V and just 0.63W, the 63 is the lowest-wattage bulb in the specifications and is physically incompatible with sockets designed for BA15s or wedge-type bulbs.
All six bulb types listed across these specifications conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical ratings within those markets.
The BA15s bayonet base, shared by the 97, 1155, and 67 bulbs, features a single contact pin and a 15mm base collar. While the shared base allows physical fitment across those three types, the wattage differences (8W, 13W, and 21W respectively) mean they are not electrically equivalent substitutes for one another.
