Plymouth Acclaim front turn signal bulbs use 3157NA, 3157, or 3057NA sizes, while rear turn signal bulbs use 3157 or 3057 sizes. The replacement chart covers 1989 to 1995 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 Acclaim uses three bulb types across its front and rear turn signal positions: 3157NA, 3157, 3057NA, and 3057. All four are T25 dual-filament wedge bulbs rated at 12V with a 27W high-filament and 7W low-filament output, conforming to ANSI standards recognized in both the United States and Canada.
The "NA" suffix in bulb designations such as 3157NA and 3057NA indicates natural amber glass. This coloring is built into the glass envelope itself rather than applied as a coating, producing the amber signal color without relying on a colored lens.
The 3157 and 3057 variants without the NA suffix use clear glass. In those applications, the amber signal color is produced by the vehicle's lens housing rather than the bulb itself.
The Plymouth Acclaim front turn signal uses the 3057NA for model years 1989-1991 and transitions to the 3157NA for 1993-1995, with 1992 using the 3157 without the NA designation.
The rear turn signal follows a parallel pattern, using the 3057 for 1989-1991 and the 3157 for 1992-1995, with no NA variants specified for any rear position.
Although the 3157 and 3057 share the same T25 wedge base and identical voltage and wattage ratings, they are not confirmed interchangeable in these specifications. The two part numbers reflect distinct ANSI designations, and fitment should correspond to the year-specific listing provided.
The dual-filament design of all four bulb types serves two functions within a single housing. The higher 27W filament activates for the turn signal flash, while the lower 7W filament typically serves as a parking or running light.
The 1992 Plymouth Acclaim front turn signal is the only model year in the front position that uses a clear 3157 rather than an NA-designated bulb, setting it apart from both the preceding and following years.
