The International C1200 uses H6024 bulbs for both high beam and low beam headlight applications, with this bulb size representing the standard specification across both lighting functions. The replacement chart covers 1963 to 1964 model years and documents the headlight bulb specifications for vehicles produced during that production period.
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 specified across all listed positions and years for the International C1200, covering both high beam and low beam headlight applications for 1963-1964.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts. It conforms to ANSI standards recognized in the United States and Canada.
A sealed beam unit differs from a conventional bulb in that the filament, reflector, and lens are fused into a single assembly. When the filament fails, the entire unit is replaced rather than an internal component.
The high beam and low beam positions on the International C1200 share the same H6024 specification for 1963-1964, indicating that a single sealed beam type serves both functions.
Because the H6024 is a sealed beam rather than a socketed bulb, fitment is governed by the physical housing and retaining ring of the headlight assembly, not by a bulb socket type.
