Mitsubishi Fuso FE-HD headlight bulb sizes include H6054 and H5001 for high beam applications, along with H6054 and H5006 for low beam applications. The replacement chart covers 1996 to 1998 model year data 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 FE-HD used three distinct sealed beam unit types across its 1996-1998 model years: H6054, H5001, and H5006, all operating at 12V and conforming to ANSI standards recognized in the United States and Canada.
All three bulb types are sealed beam units, meaning the lens, reflector, and filament are fused into a single assembly. Replacement requires substituting the entire unit rather than an internal bulb component.
The H6054 is a 5x7-inch rectangular sealed beam unit. It serves as both the high beam and low beam source on 2-headlamp configurations across all three model years.
On 4-headlamp configurations, the high beam and low beam functions are handled by separate units. The H5001, a 4-inch square sealed beam, covers the high beam role, while the H5006, a 5.75-inch round sealed beam, handles the low beam role.
The headlamp system configuration, either 2-headlamp or 4-headlamp, is the determining factor in which bulb types apply. Selecting the wrong unit for the installed configuration would result in an incorrect fitment.
The H6054 is the only unit in these specifications that performs dual beam functions within a single sealed beam assembly, serving both high and low beam positions in the 2-headlamp setup.
The H5001 and H5006 are physically distinct units with different form factors, a 4-inch square versus a 5.75-inch round housing, and are not interchangeable with each other or with the H6054.
