The International 1110 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1971 to 1973.
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 headlight positions for the International 1110, covering both high beam and low beam functions for the 1971-1973 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.
A sealed beam unit integrates the filament, reflector, and lens into a single non-serviceable assembly, meaning the entire unit is replaced rather than an internal bulb.
The International 1110 (1971-1973) uses the same H6024 specification for both the high beam and low beam headlight positions, indicating a dual-function sealed beam arrangement rather than separate single-function units.
The H6024 format was a widely standardized sealed beam type in North American vehicle production during this era, which generally supports broad cross-brand parts availability for this specification.
Because the H6024 is a sealed beam rather than a socket-based bulb, fitment is governed by the physical size and mounting configuration of the unit rather than a bulb base type.
