The Chrysler Executive Sedan uses 2057 bulb size for both front and rear turn signal applications. The replacement chart covers 1983 to 1984 model 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 2057 is the sole bulb type specified for the Chrysler Executive Sedan across all listed turn signal positions and model years.
The 2057 is an ANSI-standard bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical standards shared across those markets.
It is a dual-filament bulb, which allows a single unit to serve two distinct lighting functions, typically a brighter output for active signaling and a dimmer output for running or parking light duty.
The 2057 uses a BAY15d bayonet base, a two-pin offset base design that physically prevents incorrect insertion by positioning the two pins at different heights along the base.
The bulb operates at 12 volts with a wattage of 26.9W on its high-intensity filament and 8W on its low-intensity filament, reflecting the different power demands of each filament.
The 2057 is described as a brighter variant of the 1157, meaning the two types share the same BAY15d base but differ in output levels, which is a relevant interchangeability consideration.
Because the 1157 and 2057 share the same base type, physical fitment is possible between them, but substituting a 1157 for a 2057 would result in reduced brightness on the high-intensity filament.
The Chrysler Executive Sedan uses the same 2057 bulb specification for both the front and rear turn signals in the 1983-1984 model years, indicating no positional variation in bulb type across those locations.
