The International S132 headlight bulb uses a H6024 size for both high beam and low beam applications, with this bulb size remaining consistent across the vehicle's production specifications. The replacement chart covers 1953 to 1957 model years and documents the headlight bulb specifications for this truck model.
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 specified for the International S132 across all listed model years and positions, serving both the high beam and low beam headlight functions from 1953-1957.
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 fused glass assembly, meaning the entire unit is replaced rather than an internal bulb component.
The H6024 sealed beam format was a standardized design during this era, which means replacement units from multiple manufacturers are generally interchangeable as long as they conform to the H6024 ANSI specification.
Because the International S132 uses the same H6024 unit for both high and low beam positions, the two headlight sockets accept identical replacement parts, with no distinction between the two positions at the point of purchase.
