The International 9400 uses H6054 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1990 to 1997.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6054 is the specified bulb size for both the high beam and low beam headlight positions on the International 9400 across the 1990-1997 model years.
The H6054 is a 5x7-inch rectangular sealed beam unit, meaning the lens, reflector, and filament are fused into a single assembly rather than a separate bulb housed within a reflector housing.
Because the H6054 is a sealed beam unit, the entire assembly is replaced when the light fails, rather than replacing an individual bulb within a housing.
The H6054 operates at 12 volts and conforms to ANSI standards recognized in both the United States and Canada.
The H6054 serves both the high beam and low beam functions on the International 9400, indicating that a single sealed beam unit type handles both lighting positions rather than separate bulb types for each function.
The rectangular form factor of the H6054 is a standardized shape, which means replacement units from multiple manufacturers are generally interchangeable as long as they conform to the H6054 specification.
