The Mitsubishi Montero Sport headlight bulb specifications include 9007 and 9003 sizes for both high beam and low beam applications, with bulb configurations detailed across multiple production variants. The replacement chart covers 1997 to 2004 model years and documents the corresponding bulb size requirements for each generation.
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 model years: the 9007 for 2000-2004 and the 9003 for 1997-1999, with both types serving as dual-filament halogen bulbs that handle high and low beam functions within a single unit.
The 9007 bulb operates at 12 volts with a wattage rating of 65W on the high beam filament and 55W on the low beam filament, and it is seated in a PX29t base.
The 9003 bulb also operates at 12 volts, with a slightly higher high beam wattage of 60W and a matching low beam wattage of 55W, and it uses a P43t base rather than the PX29t found on the 9007.
Both the 9007 and 9003 are classified under ANSI standards applicable in the United States and Canada, meaning they conform to a defined set of electrical and physical standards for those markets.
Because the 9007 and 9003 use different base types, PX29t and P43t respectively, the two bulbs are not interchangeable despite sharing a similar dual-filament halogen design.
The base type difference is a critical fitment consideration for the Mitsubishi Montero Sport, as selecting a bulb from the wrong type group would result in an incompatible socket connection regardless of voltage or wattage similarity.
Both bulb types serve the same functional role across both the high beam and low beam positions, meaning the Montero Sport does not use separate single-filament bulbs for each beam function in any of its listed model years.
