International S1754 high beam and low beam headlight bulbs both use the H6024 size. The replacement chart covers vehicle production spanning 1981 to 1989.
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 S1754 spanning 1981-1989, covering both high beam and low beam functions throughout the entire model range in these specifications.
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 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 bulb element.
The H6024 serves dual duty in the International S1754, functioning as both the high beam and low beam headlight across all listed model years, which indicates the vehicle used a single sealed beam per side rather than separate housings for each function.
The ANSI standardization of the H6024 means the unit conforms to fixed dimensional and performance specifications, making it interchangeable across any vehicle that calls for the same designation regardless of manufacturer.
Because the H6024 is a standardized sealed beam format, aftermarket and OEM-equivalent units from multiple suppliers are generally available as direct replacements, provided they carry the H6024 designation.
