Mitsubishi Galant front and rear side marker bulb sizes include 168, 1034NA, 1157NA for front applications and 168, 2057, 194 for rear applications. The replacement chart covers vehicle production spanning 1985 to 2012.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 and 194 bulbs are both T10 miniature wedge types operating at 12V, though they differ in wattage. The 168 draws 4.9W while the 194 draws 3.78W, making them physically similar but not electrically identical.
The Mitsubishi Galant front side marker uses the 168 bulb across 2004-2009 model years, though this fitment is conditional on the presence of projector-type headlamps.
The 1034NA and 1157NA bulbs share the same BAY15d bayonet base and dual-filament construction, and both feature natural amber glass. The 1034NA is classified as a variant of the 1157, with the same 21W/5W filament ratings.
The 2057 rear side marker bulb carries a higher wattage output of 26.9W/8W compared to the 1157-based types, and is described as a brighter variant of the 1157 while retaining the BAY15d bayonet base.
Because the 1034NA, 1157NA, and 2057 all share the BAY15d bayonet base, physical fitment across these types may be possible, but their differing wattage ratings mean they are not direct electrical equivalents and should not be treated as interchangeable.
The rear side marker on the Mitsubishi Galant shifted from the 2057 dual-filament bulb in 1999-2003 to the single-filament 168 wedge bulb in 2004-2012, representing a significant change in both base type and filament configuration.
The front side marker for 2003-2004 model years used different bulb types. The 2003 used the 1034NA while the 2004 adopted the 168 with projector-type headlamps, indicating a transition between two incompatible base types across those years.
The 194 wedge bulb appeared in the front side marker position across 1989-1994 model years and in the rear side marker across several years in the same general era, making it one of the recurring types in earlier Galant generations.
Natural amber glass on the 1034NA and 1157NA bulbs produces an amber output from a clear lens housing, distinguishing them from standard clear-glass variants of the same base type that would require an amber lens to meet side marker color requirements.
The rear side marker on the 1988 Galant used the 194 bulb, while the front used the 168, meaning the two positions required different bulb types in that model year despite both being T10 wedge formats.
