Dodge Dart front and rear turn signal bulbs utilize sizes 7444NA, 1034NA, 1034, and 1157 depending on location and model generation. The replacement chart covers 1960 through 2016 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 7444NA is a T20 wedge-type dual-filament bulb rated at 12V with a 21W high filament and 5W low filament. Its wedge base design differs from the bayonet-style bases found in the other bulbs listed in these specifications.
The Dodge Dart (2013-2016) uses the 7444NA for the front turn signal. This bulb features natural amber glass, meaning the amber color is produced by the glass itself rather than by a colored lens or coating.
The 1034NA and 1034 are both dual-filament bulbs sharing the BAY15d bayonet base and the same 12V, 21W/5W electrical ratings. The sole distinction between them is that the 1034NA incorporates natural amber glass, while the 1034 does not.
The BAY15d bayonet base uses two offset pins at different heights to ensure correct orientation during installation, preventing the high and low filaments from being connected to the wrong circuit.
Both the 1034NA and 1034 are described as variants of the 1157, meaning they share the same base type and electrical characteristics as that bulb but are not identical to it and are not listed as interchangeable with it in these specifications.
The Dodge Dart (1960-1965) uses the 1034 for the front turn signal, while the 1966-1976 models use the 1034NA in that same position. Both share identical electrical ratings, with the only difference being the amber glass on the NA variant.
The rear turn signal on the Dodge Dart shifted from the 1034 to the 1157 between the 1968 and 1969 model years. Although both bulbs use the BAY15d base and operate at 12V/21W/5W, they are distinct part numbers and are not listed as interchangeable.
The 1157 is used exclusively in the rear turn signal position on the Dart (1969-1971 and 1976), while the 1034 and 1034NA appear across both front and rear positions in earlier model years.
All four bulb types in these specifications are dual-filament designs, which allows a single bulb to serve both a steady running light function on the low filament and a flashing turn signal function on the high filament.
All bulbs listed conform to ANSI standards applicable in both the United States and Canada, indicating they meet a common North American specification for electrical and physical compatibility.
