The International A110 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1957 to 1958 vehicle production years with corresponding bulb size 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 headlight positions for the International A110, covering both 1957-1958 model years.
The H6024 is an ANSI-standard sealed beam unit used in both the United States and Canada. It operates at 12 volts and follows the 7-inch round sealed beam format that was common in mid-20th century vehicle lighting.
Unlike modern bulb-and-housing systems, the H6024 is a sealed beam unit, meaning the lens, reflector, and filament are fused into a single assembly. When the filament fails, the entire unit requires replacement rather than just the bulb.
The H6024 is shared across both the high beam and low beam headlight positions on the International A110. In 7-inch round sealed beam designs, a single unit commonly houses both filaments, serving dual functions within one assembly.
Because the H6024 specification is identical across all listed positions and years for the International A110, there are no documented fitment variations between the 1957 and 1958 model years for this vehicle.
