International Scout II high beam and low beam headlight bulbs both utilize the H6024 size. The replacement chart covers vehicle production spanning 1971 to 1980.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International Scout II uses the H6024 bulb size for both high beam and low beam headlights across all model years from 1971-1980.
The H6024 is a 7-inch round sealed beam unit, meaning the lens, reflector, and filament are fused into a single glass assembly rather than housing a separate replaceable bulb inside.
When a filament fails in an H6024 unit, the entire sealed beam assembly is replaced rather than an individual bulb.
The H6024 operates on 12 volts and conforms to ANSI standards recognized in both the United States and Canada.
Because the same H6024 unit serves both the high beam and low beam positions on the International Scout II, a single part number covers all headlight replacements on the vehicle.
The 7-inch round sealed beam format was a standardized size widely adopted in North American vehicle manufacturing, which means H6024 units produced by different manufacturers are generally interchangeable within that standard.
