The Hino FE2618 high beam headlight uses an H4651 bulb size while low beam headlights require either H4656 or H4652 bulb sizes. The replacement chart covers vehicle production years from 1993 to 1995 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hino FE2618 uses H4651 sealed beam units for high beam headlights across the 1993-1995 model years, making it the most consistently specified bulb type in these headlight specifications.
The H4651, H4652, and H4656 are all ANSI-standardized 4x6-inch rectangular sealed beam units operating at 12V. ANSI standardization means these units conform to a defined size and interface shared across many North American vehicle applications.
All three bulb types are sealed beam units, meaning the lens, reflector, and filament are fused into a single glass assembly. When the filament fails, the entire unit requires replacement rather than just an internal bulb.
The H4652 is a variant of the H4651. Although both share the same 4x6-inch rectangular sealed beam format and 12V rating, they are distinct part numbers and are not necessarily interchangeable without confirming fitment for the specific application.
The low beam headlight specification for the Hino FE2618 (1994) calls for the H4652, while the 1993 and 1995 model years use the H4656. This means the low beam unit is not uniform across the three-year span covered by these specifications.
The H4651 and H4656 share the same physical format and voltage rating but carry different ANSI designations, which typically indicates differences in light output, beam pattern, or filament configuration. Substituting one for the other is not supported by these specifications.
