International 4900 high beam and low beam headlight assemblies utilize H6054 bulb size specifications. The replacement chart covers vehicle production spanning 1992 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 sole bulb type listed across all headlight positions for the International 4900, covering both high beam and low beam functions for the 1992-1997 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 replaceable bulb inside a housing.
When an H6054 unit fails, the entire sealed beam assembly is replaced rather than an individual bulb element.
The H6054 operates at 12 volts, which is standard for automotive electrical systems of this type.
The H6054 conforms to ANSI standards recognized in both the United States and Canada, placing it within a regulated specification for size, output, and fitment.
The International 4900 uses the same H6054 unit for both high beam and low beam functions, indicating a dual-filament sealed beam design where a single physical unit serves both lighting modes.
