Mitsubishi Montero Headlight Bulb Size

Mitsubishi Montero high beam and low beam headlight bulbs utilize 9003, 9004, or H6024 size specifications depending on model generation. The replacement chart covers vehicle production years spanning 1983 to 2006 with corresponding bulb size data.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Mitsubishi Montero headlight specifications span the 1983-2006 model years, with three distinct bulb types used across that period: H6024, 9004, and 9003.
The 9003 is a dual-filament halogen bulb rated at 12V with a 60W high beam filament and a 55W low beam filament, using a P43t base. It serves both the high beam and low beam functions in a single unit, and the Mitsubishi Montero uses it across the 1998-2006 model years.
The 9004 is also a dual-filament halogen bulb operating at 12V, but it carries a higher wattage on the high beam filament at 65W and a lower wattage on the low beam filament at 45W, with a P29t base. It is specified for the 1992-1997 model years.
The P43t and P29t base designations on the 9003 and 9004 respectively are physically incompatible with each other, meaning the two bulb types are not interchangeable despite both being dual-filament halogen units operating at 12V.
The H6024 is a 7-inch round sealed beam unit rated at 12V, used on the 1983-1991 model years. Unlike the 9003 and 9004, it is not a replaceable bulb within a housing; the entire sealed unit is replaced when the light fails.
Because the H6024 is a sealed beam unit and the 9004 and 9003 are socket-based halogen bulbs, the headlight housing design changed between the 1991 and 1992 model years, and components from these two generations are not interchangeable.
The 9003 and 9004 are both ANSI-standard bulbs recognized in the United States and Canada, while the H6024 sealed beam unit is also an ANSI-standard format common to that era of North American vehicle lighting.
For all model years covered in the specifications, the same bulb type serves both the high beam and low beam functions, reflecting the dual-filament nature of the 9003 and 9004, and the all-in-one design of the H6024 sealed beam.
