The International 7700 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 2005 to 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6024 is an ANSI-standard 7-inch round sealed beam unit rated at 12V, used across both high beam and low beam positions in the International 7700 for the 2005-2007 model years.
Unlike bulb-based headlight systems, the H6024 is not a replaceable bulb. When the light fails, the entire sealed beam unit requires replacement.
The H6024 specification applies to both the high beam and low beam headlight positions, meaning a single bulb type serves both functions in the International 7700.
The H6024 standard is recognized in both the United States and Canada, reflecting a shared ANSI specification across North American markets.
The 7-inch round form factor of the H6024 is a long-established sealed beam format, and fitment depends on this physical housing size rather than a separate bulb socket or base type.
