The Mitsubishi Expo side marker requires a bulb size of 12961 for the lighting assembly. Data for the specific component covers the period from 1995 through 1995.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Expo uses two bulb types across its side marker positions: the 168 and the 194. Both are ANSI-standardized miniature wedge bulbs of the T10 form factor, rated at 12 volts.
The 168 and 194 bulbs share the same T10 wedge base, which means they are physically interchangeable in terms of socket fit. However, their wattage ratings differ, with the 168 drawing 4.9W and the 194 drawing 3.78W.
Because the 168 and 194 occupy the same T10 socket, the distinction between them in these specifications is one of wattage output rather than physical form factor.
The 1992-1994 Mitsubishi Expo uses the 194 bulb for both the front and rear side marker positions.
The 1995 Mitsubishi Expo uses the 168 bulb for both the front and rear side marker positions, representing a shift from the 194 used in prior model years.
The front and rear side marker positions share the same bulb type within any given model year across the full 1992-1995 production span covered by these specifications.
Both the 168 and 194 are governed by ANSI standards applicable in the United States and Canada, indicating a standardized performance and dimensional classification for North American market vehicles.
