The Mitsubishi Montero Sport front side marker bulb uses 7443 or 168 size, while the rear side marker bulb uses 168 size. The replacement chart covers 1997 to 2004 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 Mitsubishi Montero Sport uses two distinct bulb types across its side marker positions: the 7443 and the 168, both of which conform to ANSI standards applicable in the United States and Canada.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W, making it a low-wattage single-filament lamp suited to side marker applications.
The 7443 bulb is a T20 wedge type with a dual-filament configuration rated at 12V and 21W/5W, meaning it carries two separate filaments operating at different wattages within a single housing.
The rear side marker position on the Mitsubishi Montero Sport uses the 168 bulb across all model years covered, spanning 1997-2004.
The front side marker position shifted from the 168 bulb on 1997-1999 models to the 7443 bulb on 2000-2004 models, indicating a change in the front lighting assembly between those production periods.
The 7443 is a dual-filament bulb, while the 168 is a single-filament type. These two bulbs are not interchangeable, as their filament count, wattage, and physical base configurations differ despite both being wedge-style lamps.
Installing a 168 in a socket designed for a 7443 would result in an incorrect fit and loss of the secondary filament function, since the T10 and T20 wedge bases are not the same size.
