The International R132 high beam and low beam headlight bulbs both utilize the H6024 bulb size. The replacement chart covers vehicle production spanning 1953 to 1955.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International R132 uses the H6024 bulb size across both the high beam and low beam headlight positions for the 1953-1955 model years.
The H6024 is an ANSI-standardized sealed beam unit used in both the United States and Canada, operating at 12 volts.
A sealed beam unit integrates the filament, reflector, and lens into a single fused glass assembly, which means the entire unit is replaced rather than an internal bulb.
The H6024 follows a 7-inch round form factor, a standardized size that was regulated under ANSI specifications for North American vehicle lighting.
Because the H6024 serves both the high beam and low beam positions on the International R132, the vehicle relies on a dual-filament sealed beam design, where a single unit contains separate filaments for each function.
The shared H6024 specification across both beam positions means the same replacement unit is interchangeable between the high beam and low beam housings on this vehicle.
