Mitsubishi Fuso FM-MR headlight bulbs utilize H6054 and H5001 sizes for high beam applications, with H6054 and H5006 sizes for low beam configurations. The replacement chart covers 1996 to 1998 production years and details bulb size specifications across the model range.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Fuso FM-MR was produced across the 1996-1998 model years according to these specifications, with headlamp bulb requirements remaining consistent across all three years.
The FM-MR was offered in two distinct headlamp configurations: a 2-headlamp system and a 4-headlamp system, each requiring different bulb types depending on the arrangement.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V and conforming to ANSI standards applicable in the US and Canada. It serves as both the high beam and low beam bulb in the 2-headlamp configuration, meaning a single unit type handles both functions.
In the 4-headlamp configuration, the high beam and low beam functions are handled by separate bulb types. The H5001 is assigned to high beam duty, while the H5006 handles low beam duty.
The H5001 is a 4-inch square sealed beam unit at 12V, and the H5006 is a 5.75-inch round sealed beam unit also at 12V, both conforming to ANSI standards. Their differing shapes and sizes make them non-interchangeable with each other and with the H6054.
All three bulb types, H6054, H5001, and H5006, are sealed beam units. In a sealed beam design, the lens, reflector, and filament are fused into a single assembly, so the entire unit is replaced rather than an individual bulb.
Because the 2-headlamp and 4-headlamp systems use physically different sealed beam units with distinct form factors, parts sourced for one configuration are not compatible with the other.
