The International 1010 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 1010, covering model years 1971-1973.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts. It conforms to ANSI standards as recognized in both the United States and Canada.
A sealed beam unit is a self-contained assembly in which the filament, reflector, and lens are fused into a single glass envelope. Because of this construction, the H6024 is replaced as a whole unit rather than by swapping an internal bulb.
The H6024 serves both the high beam and low beam headlight positions on the International 1010 for all three listed model years, meaning a single bulb type covers the full headlight system.
The sealed beam format of the H6024 means fitment is governed by the physical housing size and electrical rating of the unit. A 7-inch round sealed beam is a standardized form factor, and substitutions must match both the physical size and the 12-volt rating to be compatible.
