The International B132 headlight bulb uses a H6024 size for both high beam and low beam functions. The replacement chart covers 1959 to 1960 vehicle production years with corresponding bulb 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 12V. It follows the ANSI standard used in the United States and Canada, meaning the entire housing, lens, and filament are fused into one unit. When the filament fails, the whole assembly is replaced rather than an individual bulb.
The International B132 uses the H6024 for both high beam and low beam headlight positions across the 1959-1960 model years, with no distinction between the two functions in terms of bulb type.
Because the H6024 is a sealed beam unit rather than a socketed bulb, fitment is determined by the physical size and mounting configuration of the 7-inch round format rather than by a separate bulb socket or base type.
The shared H6024 specification across both beam positions suggests the B132 used a four-headlight arrangement or a dual-filament sealed beam, both of which were common configurations for ANSI-standardized sealed beam systems of that period.
