The International L112 headlight bulb utilizes the H6024 size for both high beam and low beam functions. The replacement chart covers 1950 to 1952 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-and-reflector assemblies, the sealed beam design integrates the filament, reflector, and lens into a single unit, meaning the entire assembly is replaced rather than an internal bulb.
The International L112 uses the H6024 for both high beam and low beam headlight positions across the 1950-1952 model years. A single bulb type serving both functions in this way is characteristic of early sealed beam systems, where one unit housed dual filaments to produce both beam modes.
Because the H6024 follows an ANSI-standardized form factor, units from different manufacturers sharing that designation are generally interchangeable, provided they meet the same voltage and physical specifications.
