Dodge Lancer front and rear side marker bulbs utilize a 168 size bulb across all positions. The replacement chart covers 1985 to 1989 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 Dodge Lancer uses the 168 bulb for both front and rear side marker positions across the 1985-1989 model years.
The 168 is an ANSI-standardized bulb recognized across the United States and Canada, operating at 12 volts with a power draw of 4.9 watts.
The 168 follows the T10 form factor, a miniature wedge-base design that seats without a twist-lock mechanism, relying instead on socket tension to hold the bulb in place.
Because the same bulb size applies to all five model years in both marker positions, a single 168 bulb serves as a direct replacement for any side marker socket on the 1985-1989 Dodge Lancer.
The T10 wedge base is a widely produced format, and the 168 designation is interchangeable with several other bulbs sharing the same base and voltage rating, though wattage differences among alternatives may affect brightness and socket compatibility.
