Plymouth Scamp front and rear side marker bulbs utilize 168 or 1895 bulb sizes across the vehicle's production span. The replacement chart covers 1971 through 1983 model 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 Scamp uses two distinct bulb types across its side marker positions: the 168 and the 1895, both of which conform to ANSI standards recognized in the United States and Canada.
Both bulb types share the miniature wedge base design, though they belong to different T-series classifications. The 168 is a T10 wedge, while the 1895 is a T5 wedge, making the two physically incompatible with each other despite their similar base style.
The 168 bulb operates at 12V and draws 4.9W, whereas the 1895 operates at 12V but draws only 0.9W, a notably lower wattage that reflects its smaller T5 form factor.
For the Plymouth Scamp, the 1895 bulb applies to both the front and rear side marker positions for the 1971-1972 model years.
The 168 bulb applies to both the front and rear side marker positions for the 1973-1976 and 1983 model years of the Scamp.
The front and rear side marker positions on the Plymouth Scamp share the same bulb size for every model year listed in the specifications, meaning no asymmetry exists between front and rear fitment within any given year.
The T10 wedge form factor of the 168 bulb is physically larger than the T5 form factor of the 1895. Substituting one for the other would result in an incorrect fit within the socket housing.
The wattage difference between the 168 and 1895 bulbs is significant at roughly 4W. Installing a higher-wattage bulb in a socket rated for a lower-wattage type can generate excess heat within the housing.
