The Plymouth Prowler side marker requires a 168 bulb size for proper installation and function. Data for the specified lighting component covers the period from 1997 through 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Prowler uses the 168 bulb size across all listed model years for both front and rear side marker positions.
The 168 bulb is an ANSI-standardized type recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
It is a miniature wedge-style bulb, classified under the T10 designation, which refers to its tubular glass envelope width of 10 millimeters expressed in eighths of an inch.
The wedge base design means the bulb is held in its socket by the tension of the base itself rather than by a separate metal contact pin, which is a common trait in low-wattage automotive lighting applications.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of side marker and courtesy lighting rather than primary illumination functions.
The Plymouth Prowler (1997-2001) uses the same 168 bulb specification for both the front and rear side marker positions, indicating a uniform fitment across both locations on the vehicle.
The T10 wedge form factor is widely shared among automotive bulb types, and certain substitute designations such as the 194 are physically compatible but differ in wattage, which can affect circuit load and brightness.
Because the 168 and 194 share the same T10 wedge base, they are sometimes treated as interchangeable in practice, though the 194 is rated at 3.78 watts rather than 4.9 watts, producing a measurable difference in light output.
