Additional Notes

The H6024 is a 7-inch round sealed beam unit operating at 12V, conforming to ANSI standards recognized in both the United States and Canada.
Unlike bulb-based headlight assemblies, the H6024 is a sealed beam unit, meaning the entire assembly is replaced rather than an internal bulb.
The International S1823 uses the H6024 for both high beam and low beam headlight positions across the 1980-1982 model years.
Because the same H6024 unit serves both beam functions, the high and low beam positions are interchangeable with the same replacement part.
