The International S102 headlight bulb uses a H6024 size for both high beam and low beam applications. The replacement chart covers vehicle production spanning 1956 to 1957.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts. It conforms to ANSI standards as recognized in the United States and Canada. Because the light source is fused permanently within the housing, the entire unit is replaced rather than an internal bulb.
The International S102 uses the H6024 for both high beam and low beam headlight positions across the 1956-1957 model years. A single bulb type serving dual beam functions in this way is a characteristic of sealed beam technology from that era, where separate filaments within one unit handle each lighting mode.
The sealed beam format of the H6024 means fitment is defined by the physical housing rather than a socket or base type. Any replacement unit must match the 7-inch round form factor and ANSI H6024 designation to seat correctly in the International S102 headlight assembly.
