The International R130 headlight bulb uses a H6024 size for both high beam and low beam applications. 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 H6024 is the sole bulb type listed across all headlight positions in these specifications, appearing in both the high beam and low beam roles for the International R130 across the 1953-1955 model years.
The H6024 is a 7-inch round sealed beam unit built to ANSI standards recognized in the United States and Canada. It operates on a 12-volt electrical system.
A sealed beam unit differs from a conventional bulb in that the filament, reflector, and lens are fused into a single glass assembly. When the filament fails, the entire unit is replaced rather than an internal component.
Because the H6024 serves both the high beam and low beam positions in these specifications, the same sealed beam unit is used across both lighting functions, which was a common arrangement in mid-20th century sealed beam headlight systems where a single filament unit handled one beam mode per housing.
The ANSI standardization of the H6024 means the unit conforms to a defined physical and electrical specification, which historically allowed interchangeability across different vehicle makes and models using the same standard.
