Plymouth Sundance front and rear side marker bulbs utilize 168 and 916 bulb sizes depending on location and model variation. The replacement chart covers vehicle production spanning 1987 to 1994 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 Sundance uses two bulb types across its side marker positions: the 168 and the 916, both of which conform to ANSI standards recognized in the United States and Canada.
The 168 is a miniature wedge bulb in the T10 form factor, rated at 12 volts and 4.9 watts. The T10 designation refers to a tubular bulb with a width of roughly 10 millimeters at its widest point, fitted with a wedge-style base that requires no separate socket locking mechanism.
The 916 is a wedge bulb in the T15 form factor, also rated at 12 volts but drawing 18 watts. The T15 is physically larger than the T10, and the difference in wattage means the two types are not interchangeable despite sharing the same wedge base style.
The Plymouth Sundance front side marker position uses the 168 bulb across all model years from 1987-1994, indicating no change in front side marker specification throughout the vehicle's production run.
The rear side marker specification for the Plymouth Sundance differs by year. The 1987-1988 model years use the 168 bulb, while the 1989-1993 model years use the 916 bulb, and the 1994 model year returns to the 168 bulb.
Because the rear side marker socket changed between certain model years, a 916 bulb from a 1989-1993 Sundance is not a direct fit for the 1987-1988 or 1994 rear side marker positions, even though all three share a wedge base construction.
The wattage difference between the 168 (4.9W) and the 916 (18W) is substantial. Installing a higher-wattage bulb in a socket rated for a lower-wattage type risks overheating the socket housing and surrounding wiring.
