The International C132 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1961 to 1962 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 12 volts. It conforms to ANSI standards as recognized in the United States and Canada. Unlike bulb-based housings, the sealed beam design integrates the filament, reflector, and lens into a single unit, meaning the entire assembly is replaced rather than an individual bulb.
The International C132 uses the H6024 for both the high beam and low beam headlight positions across the 1961-1962 model years. A single bulb type serving both functions is characteristic of early sealed beam systems, where one unit handled the full headlight role.
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 unit itself. The 7-inch round format was a standardized size during this period, which generally allowed interchangeability between vehicles using the same sealed beam specification.
