Mitsubishi Fuso FM-HR headlight bulb sizes include H6054 and H5001 for high beam applications, with H6054 and H5006 for low beam configurations. The replacement chart covers 1996 through 1998 production years and contains bulb size specifications for each beam type.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Fuso FM-HR used two distinct headlamp configurations across the 1996-1998 model years: a two-headlamp system and a four-headlamp system, each requiring different sealed beam units depending on the position and configuration.
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 unit in the two-headlamp configuration, meaning a single unit type handles both functions in that setup.
In the four-headlamp configuration, the high beam and low beam positions use separate and distinct sealed beam types. The H5001 handles high beam duties while the H5006 handles low beam duties, and these two units are not interchangeable with each other.
The H5001 is a 4-inch square sealed beam unit, also ANSI-rated and operating at 12V. The H5006 is a 5.75-inch round sealed beam unit sharing the same voltage and standards compliance.
All three bulb types, H6054, H5001, and H5006, are sealed beam units rather than housings with replaceable bulbs. When a sealed beam fails, the entire unit is replaced rather than an internal filament or capsule.
The physical form factors of the three sealed beam types differ substantially. The rectangular H6054, the square H5001, and the round H5006 are not dimensionally compatible with one another, and substitution between them is not supported by the specifications.
