Plymouth Fleet Special front and rear turn signal bulbs both use 1034 size bulbs. The replacement chart covers 1960 to 1963 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 Fleet Special uses the 1034 bulb in both the front and rear turn signal positions across the 1960-1963 model years.
The 1034 is an ANSI-standardized bulb type recognized in both the United States and Canada.
It is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, allowing it to serve more than one lighting function.
The 1034 operates on a 12-volt electrical system and carries a 21/5-watt rating, where the higher wattage corresponds to the brighter filament and the lower to the dimmer one.
The 1034 uses a BAY15d bayonet base, a two-pin base type in which the two pins are offset at different heights to ensure correct orientation during installation.
The 1034 is a variant of the 1157 bulb. While the two share the same BAY15d base, they differ in wattage, and this distinction makes them non-interchangeable in applications where precise wattage is a factor.
