Plymouth Fury III front turn signal bulbs utilize 1157NA, 1157, or 1034NA bulb sizes, while rear turn signal bulbs use 1157 or 1034 sizes. The replacement chart covers 1965 through 1974 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Fury III uses two bulb types across its front and rear turn signal positions: the 1157 family and the 1034 family, both of which are dual-filament bulbs rated at 12V with a 21W high-filament and 5W low-filament output.
All four bulb types listed in these specifications share the BAY15d bayonet base, a double-contact offset-pin base that physically locks the bulb into position and ensures correct filament orientation within the socket.
The 1034 and 1034NA are classified as variants of the 1157, meaning they share the same base type and general electrical ratings but are distinct ANSI part numbers and are not guaranteed to be interchangeable without verification.
The "NA" suffix on the 1157NA and 1034NA designates natural amber glass, meaning the amber color is produced by the glass envelope itself rather than by a coated or painted lens or housing.
For the Plymouth Fury III (1965-1970), the front turn signal position calls for the 1034NA, while the rear uses the clear-glass 1034, indicating that the amber coloring at the front was handled at the bulb level during those model years.
For 1971-1972, the front turn signal shifted to the 1157, a clear-glass bulb, while the rear retained the 1157 as well, representing a change from the 1034-series used in earlier model years.
For 1973-1974, the front turn signal position specifies the 1157NA, reintroducing a natural amber glass bulb at the front after the clear-glass 1157 was used in 1971-1972.
All bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada, indicating a standardized electrical and physical specification recognized across North American markets.
Because the 1034 and 1157 families share the BAY15d base and identical voltage and wattage ratings, physical fitment into the socket may be possible across types, but substitution between them is not supported by these specifications.
The rear turn signal on the Plymouth Fury III follows a parallel pattern to the front across all listed model years, with the 1034 used from 1965-1970 and the 1157 from 1971-1974, though the rear positions consistently use clear-glass variants rather than NA-suffix bulbs.
