Oldsmobile Starfire License Plate Bulb Size

Additional Notes

• The Oldsmobile Starfire uses four distinct bulb sizes across its production years for the license plate position: the 194, 97, 1155, and 67.
• The 67 bulb is the most frequently specified across the Starfire's model years, covering the 1954-1957 and 1961-1963 model years.
• All four bulb types in these specifications conform to ANSI standards recognized in both the United States and Canada.
• The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, making it among the lowest-wattage options in this specification set. The Oldsmobile Starfire uses it across the 1975-1980 model years.
• The 67, 97, and 1155 bulbs all share the BA15s single-contact bayonet base, meaning they are physically similar in mounting style but are not interchangeable due to differing wattage ratings.
• The 67 bulb operates at 8W, the 97 at 13W, and the 1155 at 21W, representing a significant range of power consumption despite their shared base type.
• The 1155 is the highest-wattage bulb in these specifications at 21W and is used exclusively on the 1964 Starfire for the license plate position.
• The 97 bulb, used on the 1965-1966 Starfire, is a variant of the 1156 family, as are the 67 and 1155, though each carries a distinct wattage that determines its correct application.
• The T10 wedge format of the 194 bulb differs fundamentally from the BA15s bayonet base shared by the other three bulb types, making cross-substitution between the 194 and the remaining bulbs physically incompatible.
• The 1954 Starfire and the 1980 Starfire represent the earliest and latest model years in these specifications, with each requiring a different bulb size for the license plate position.
