International Scout high beam and low beam headlight bulbs both utilize the H6024 size. The replacement chart covers vehicle production spanning 1961 to 1971.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International Scout uses the H6024 bulb size for both high beam and low beam headlights across all listed model years, spanning 1961-1971.
The H6024 is an ANSI-standardized sealed beam unit, meaning the lens, reflector, and filament are fused into a single non-serviceable assembly. When the filament fails, the entire unit is replaced rather than an internal bulb.
The H6024 unit is a 7-inch round sealed beam operating at 12 volts, a format that was widely adopted across North American vehicle production during this era and governed by shared ANSI standards applicable in both the United States and Canada.
Because the International Scout (1961-1971) uses the same H6024 specification for both the high beam and low beam positions, the vehicle relies on the dual-filament capability built into the sealed beam unit itself rather than separate single-filament assemblies for each function.
The ANSI standardization of the H6024 means that units produced by different manufacturers to this specification are dimensionally and electrically interchangeable, provided they conform to the same standard.
