The International 7400 uses H6024 bulb size for both high beam and low beam headlight applications. Replacement chart data covers 2008 to 2017 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International 7400 uses the H6024 bulb for both high beam and low beam headlights across the 2008-2017 model years.
The H6024 is a sealed beam unit, meaning the lens, reflector, and filament are fused into a single non-serviceable assembly rather than a replaceable bulb within a separate housing.
Sealed beam units such as the H6024 operate on a standardized 7-inch round format, which allows for cross-brand fitment compatibility as long as the H6024 designation is matched exactly.
The H6024 carries a dual-filament design, which is what allows a single sealed beam to serve both the high beam and low beam functions in the International 7400.
Because the same H6024 part number is specified for both beam positions across all listed years, only one bulb type is required to service either headlight function on the 7400.
The H6024 designation follows ANSI standardization, which means replacement units from different manufacturers are generally interchangeable as long as they carry the same H6024 rating.
Substituting a visually similar sealed beam with a different designation, such as the H6012 or H6014, would not be appropriate, as those types carry different wattage ratings and single-filament configurations incompatible with the dual-beam requirement of the International 7400.
