Chrysler E Class front and rear turn signal bulbs utilize 2057NA and 2057 sizes respectively, with the front bulb featuring a distinct larger configuration than the rear bulb size. The replacement chart covers 1983 to 1984 model production years and documents turn signal bulb specifications for this vehicle generation.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler E Class uses the 2057NA bulb for the front turn signal across both the 1983-1984 model years.
The 2057NA is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a wattage of 26.9W on the high filament and 8W on the low filament.
The "NA" suffix in the 2057NA designation indicates natural amber glass, meaning the bulb produces an amber color without relying on a colored lens.
The rear turn signal on the 1983-1984 Chrysler E Class uses the 2057 bulb, which shares the same dual-filament BAY15d bayonet base and 12V/26.9W/8W electrical ratings as the 2057NA.
The primary distinction between the front and rear turn signal bulbs is the amber glass coating present on the 2057NA but absent on the 2057, which uses clear glass.
Both the 2057 and 2057NA are ANSI-standardized bulbs recognized in the US and Canada, and both are described as brighter variants of the widely used 1157 bulb type.
Because the 2057NA and 2057 share the same BAY15d base and voltage ratings, they are physically interchangeable, though substituting a clear 2057 in a front position designed for the 2057NA may affect the amber color output if the lens itself is not amber-tinted.
