The Chrysler TC Maserati uses a 2057 bulb size for both front and rear turn signal applications. The replacement chart covers 1989 to 1991 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 bulb is the sole bulb type specified for the Chrysler TC Maserati across all listed turn signal positions and model years.
The 2057 is a dual-filament bulb, meaning it serves two lighting functions within a single unit, operating separate filaments at different wattages.
It operates on a 12-volt system with a wattage rating of 26.9W on the high filament and 8W on the low filament, reflecting its dual-function design.
The 2057 uses a BAY15d bayonet base, a two-pin offset base type that physically prevents incorrect insertion by positioning the two pins at different heights.
It conforms to ANSI standards and is recognized in both the United States and Canada, indicating standardized electrical and photometric performance requirements.
The 2057 is described as a brighter variant of the 1157 bulb. While the two types share the same BAY15d base and are physically interchangeable in many sockets, the 1157 carries a higher wattage on its high filament, making the two electrically distinct.
Because the 2057 and 1157 differ in wattage output, substituting one for the other in the Chrysler TC Maserati (1989-1991) may affect light intensity and could influence turn signal flash rate if the vehicle uses a load-sensitive flasher relay.
The 2057 specification applies uniformly to both the front and rear turn signal positions across the 1989-1991 model years, indicating no positional variation in bulb type for this vehicle.
