The International 4800 headlight bulb utilizes an H6054 size for both high beam and low beam functions. The replacement chart covers vehicle production spanning 1990 to 2003.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International 4800 uses the H6054 bulb size for both high beam and low beam headlights across all model years from 1990-2003.
The H6054 is an ANSI-standardized sealed beam unit recognized in both the United States and Canada, meaning it conforms to a regulated specification rather than a proprietary design.
As a sealed beam unit, the H6054 houses the filament, reflector, and lens within a single fused glass assembly. When the filament fails, the entire unit is replaced rather than an individual bulb.
The H6054 is a 5x7-inch rectangular sealed beam format, which is a widely used standardized size in commercial and heavy-duty vehicle applications.
The H6054 operates at 12 volts, consistent with standard automotive electrical systems.
Because the same H6054 unit serves both the high beam and low beam positions on the International 4800, the vehicle relies on a dual-filament or separate-unit arrangement within that sealed beam format rather than distinct bulb types for each function.
The ANSI standardization of the H6054 means that units from different manufacturers sharing that designation are generally interchangeable, provided they meet the same voltage and physical format requirements.
