The Mitsubishi Fuso FM-SP high beam headlight uses H6054 or H5001 bulb sizes, while the low beam headlight requires H6054 or H5006 bulb sizes. The replacement chart covers 1996 to 1998 vehicle production 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 Fuso FM-SP for model years 1996-1998 uses two distinct headlamp configurations: a 2-headlamp system and a 4-headlamp system, each requiring different bulb types across both high and low beam positions.
The H6054 is a 5x7-inch rectangular sealed beam unit conforming to ANSI standards applicable in the US and Canada. It operates at 12V and serves as both the high beam and low beam bulb in the 2-headlamp configuration across all three model years.
In the 4-headlamp configuration, the high beam position uses the H5001, a 4-inch square sealed beam unit, also ANSI-standardized and rated at 12V.
The low beam position in the 4-headlamp configuration uses the H5006, a 5.75-inch round sealed beam unit, ANSI-standardized and rated at 12V.
All three bulb types, H6054, H5001, and H5006, are sealed beam units. The entire unit is replaced rather than an internal filament or capsule, which distinguishes them from halogen or other replaceable-bulb housings.
The H6054 is the only bulb type shared across both the high beam and low beam functions, a characteristic specific to the 2-headlamp system where a single sealed beam handles both duties through separate filaments within the unit.
The rectangular form factor of the H6054 differs from the square H5001 and round H5006 used in the 4-headlamp system, meaning the three types are not interchangeable despite sharing the same 12V rating and ANSI classification framework.
Selecting the correct bulb type for the FM-SP requires confirming whether the vehicle is equipped with 2 or 4 headlamps, as the fitment diverges entirely between the two configurations at both beam positions.
