Additional Notes

The Oldsmobile Cutlass license plate bulb specifications span the 1961-1999 model years, with four distinct bulb types represented across that range: the 194, 97, 1155, and 67.
The 194 is the most frequently specified bulb in the Oldsmobile Cutlass license plate fitment data, covering the 1974-1981 and 1997-1999 model years. It is a T10 miniature wedge-base bulb rated at 12V and 3.78W, conforming to ANSI standards for the US and Canadian markets.
The 97 bulb is the second most commonly specified type, fitted to the Cutlass across the 1965-1973 model years. It uses a BA15s single-contact bayonet base, operates at 12V, and draws 13W, making it a notably higher-wattage unit than the 194.
The 67 bulb is specified for the 1961-1963 Cutlass. Like the 97 and 1155, it uses a BA15s bayonet base and operates at 12V, but its 8W rating places it at the lower end of the wattage range among the BA15s variants listed in these specifications.
The 1155 bulb is specified exclusively for the 1964 Cutlass. It shares the BA15s bayonet base with the 97 and 67 but carries a 21W rating, the highest wattage of any bulb in these specifications.
The 97, 1155, and 67 are all described as variants of the 1156 bulb family, sharing the same BA15s single-contact bayonet base. Despite this shared base type, their wattage ratings differ substantially at 13W, 21W, and 8W respectively, and they are not interchangeable without accounting for those electrical differences.
The 194 wedge-base format and the BA15s bayonet-base format represent two physically incompatible mounting systems. A 194 bulb cannot be substituted into a socket designed for the 97, 1155, or 67, and vice versa.
Within the BA15s group, the shared base type does not indicate direct interchangeability. The wattage variation across the 67, 97, and 1155 reflects differing electrical loads, which can affect socket ratings and circuit compatibility.
