The International L150 uses an H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1950 to 1952.
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, standardized under ANSI specifications for the United States and Canada. Unlike conventional bulb-and-reflector assemblies, the sealed beam design integrates the filament, reflector, and lens into a single non-serviceable unit, meaning the entire assembly is replaced rather than an internal bulb.
The International L150 uses the H6024 for both high beam and low beam headlight positions across the 1950-1952 model years, with no variation in bulb type between those two functions or across those years.
Because the H6024 serves dual roles in the International L150, covering both high and low beam functions, the vehicle does not use separate bulb types for each lighting mode. This arrangement was typical of single-unit sealed beam systems where beam switching was handled internally by the unit itself through separate filaments.
The ANSI standardization of the H6024 means the unit conforms to fixed physical and electrical specifications shared across multiple vehicle applications of the era, which generally allows cross-brand interchangeability with other vehicles specifying the same H6024 designation.
