International A132 vehicles utilized 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 as recognized in the United States and Canada.
Unlike bulb-and-reflector assemblies, the H6024 is a sealed beam unit, meaning the lens, reflector, and filament are fused into a single non-serviceable housing. When the filament fails, the entire unit is replaced rather than an internal bulb.
The International A132 uses the H6024 for both high beam and low beam headlight positions across the 1957-1958 model years, making it the sole bulb type present in these specifications.
The shared H6024 fitment across both beam positions indicates the vehicle relied on a dual-filament sealed beam design, where a single unit serves switching between high and low beam output.
The ANSI designation of the H6024 reflects a standardized specification, meaning units from different manufacturers carrying the same designation are electrically and physically interchangeable.
