The International R112 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1953 to 1955 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 the sole bulb type listed across all positions in the International R112 specifications, appearing in both the high beam and low beam headlight roles for the 1953-1955 model years.
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 unit, the H6024 does not contain a separately replaceable bulb element. When the unit fails or is damaged, the entire assembly is replaced rather than an internal filament or capsule.
The International R112 uses the same H6024 specification for both high beam and low beam functions, indicating that a single sealed beam unit serves the dual lighting role rather than separate dedicated bulbs for each function.
