Plymouth Turismo front and rear side marker bulbs use a 168 bulb size across all configurations. The replacement chart covers vehicle production spanning 1983 to 1987.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Turismo uses the 168 bulb for both front and rear side marker positions across the 1983-1987 model years.
The 168 is a miniature wedge bulb built to the T10 form factor, operating at 12 volts with a power draw of 4.9 watts.
The T10 wedge base design requires no separate socket retainer or locking tab, as the bulb is held in place by friction from the housing itself.
The 168 bulb conforms to ANSI standards recognized in both the United States and Canada, placing it within a regulated performance and dimensional classification.
Because the same bulb number applies to all ten side marker positions across the full 1983-1987 production run, front and rear positions on the Plymouth Turismo share a single interchangeable bulb type.
At 4.9 watts, the 168 falls within the low-wattage range typical of marker and clearance lighting, where output requirements are lower than those of primary illumination functions such as headlamps or brake lights.
The T10 wedge format is widely shared across automotive applications, meaning the 168 bulb is not exclusive to the Plymouth Turismo and is produced by multiple manufacturers under the same ANSI designation.
When substituting bulbs in T10 wedge sockets, wattage compatibility with the original circuit is a relevant factor, as the socket and wiring are rated around the 4.9-watt load of the 168.
