The International A130 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1957 to 1958 production years 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 H6024 is a 7-inch round sealed beam unit operating at 12 volts. It conforms to ANSI standards applicable in the United States and Canada.
Unlike bulb-and-housing systems, the H6024 is a sealed beam unit in which the filament, reflector, and lens are fused into a single assembly. When the filament fails, the entire unit is replaced rather than an individual bulb.
The International A130 uses the H6024 for both high beam and low beam headlight positions across the 1957-1958 model years, meaning a single sealed beam type serves dual functions in this application.
The ANSI standardization of the H6024 means the unit conforms to a defined physical and electrical specification shared across multiple vehicle makes, which is a characteristic of the sealed beam era in North American automotive lighting.
