The Mitsubishi Montero Sport brake light utilizes a 2057 bulb size for illumination during vehicle operation. Data for the specified component covers the period from 1997 through 2004.
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 the 2057 bulb for its brake lights across the full 1997-2004 model range.
The 2057 is a dual-filament bulb with a BAY15d bayonet base, operating at 12V with filament ratings of 26.9W and 8W, where the higher wattage filament serves the brake function and the lower wattage filament serves a secondary function such as running lights.
The 2057 is a brighter variant of the 1157, meaning the two share the same BAY15d base type but are not identical in output, and substituting one for the other may produce different brightness levels.
The center high mount stop light on the Mitsubishi Montero Sport takes either a 921 or a 168 bulb depending on the model year, making direct interchangeability between all years impossible without confirming the specific year first.
The 921 is a T15 wedge bulb rated at 12V and 16W, while the 168 is a T10 miniature wedge bulb rated at 12V and 4.9W. These two bulb types differ in both physical size and wattage output, and they are not interchangeable.
The 1999-2000 and 2001-2004 center high mount stop light positions use the 921 bulb, while the 1998-1999 positions use the 168 bulb. The 1997 model year returns to the 921, indicating that the 168 was specific to a transitional period in the production run.
All three bulb types listed in these specifications, the 2057, 921, and 168, conform to ANSI standards applicable in both the United States and Canada.
