The International L111 uses H6024 bulb size for both high beam and low beam headlight applications. 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, conforming to ANSI standards recognized in both the United States and Canada.
As a sealed beam design, the H6024 does not contain a replaceable bulb element. When the unit fails, the entire assembly is replaced as a single component.
The International L111 uses the H6024 for both high beam and low beam headlight positions across the 1950-1952 model years, meaning a single bulb type serves both functions.
The shared H6024 fitment across both beam positions indicates the vehicle relied on a dual-function sealed beam unit rather than separate dedicated high and low beam assemblies.
