The Plymouth Turismo tail light requires bulb size 1157 or 2057 depending on the specific version of the vehicle. Data for the tail light covers the range from 1983 to 1985.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Turismo tail light specifications cover the 1983-1987 model years, with the outer tail light position spanning all five years and the inner tail light position applying to 1986-1987.
The outer tail light on the Plymouth Turismo uses two distinct bulb types across its production run: the 2057 for 1983-1984 and the 1157 for 1985-1987.
Both the 1157 and 2057 are dual-filament bulbs sharing the BAY15d bayonet base, meaning they physically fit the same socket. However, they are not electrically identical, as the 2057 operates at 26.9W/8W while the 1157 operates at 21W/5W.
The higher wattage of the 2057 reflects a brighter output on both filaments compared to the 1157, which is a relevant distinction for tail light and brake light intensity.
The inner tail light for 1986-1987 uses the 168, a miniature wedge-base bulb of the T10 type rated at 12V and 4.9W, a single-filament design suited to lower-intensity lighting functions.
The T10 wedge base of the 168 bulb is physically incompatible with the BAY15d bayonet base used by the 1157 and 2057, so the inner and outer tail light sockets on the 1986-1987 Turismo accept different bulb families entirely.
All three bulb types listed, the 168, 1157, and 2057, conform to ANSI standards recognized in both the United States and Canada.
The dual-filament design of the 1157 and 2057 allows a single bulb to serve two functions simultaneously, typically combining a lower-intensity running light filament with a higher-intensity brake or turn signal filament.
