International WorkStar 7600 high beam and low beam headlight bulbs both utilize the H6024 size. The replacement chart covers vehicle production spanning 2008 to 2017.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6024 is the sole bulb type specified across all headlight positions on the International WorkStar 7600, covering model years 2008-2017 for both high beam and low beam applications.
The H6024 is a sealed beam unit, meaning the lens, reflector, and filament are fused into a single 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, a design governed by long-standing regulatory specifications for commercial and heavy-duty vehicle lighting.
The H6024 carries a dual-filament design, which allows a single sealed beam unit to serve both high and low beam functions from within the same assembly.
Because the H6024 is used for both the high beam and low beam positions on the WorkStar 7600, the vehicle relies on the same physical unit across both lighting circuits.
The H6024 designation is specific to a sealed beam with a particular filament configuration and should not be substituted with visually similar sealed beams such as the H6012 or H6014, which carry different filament arrangements and are not interchangeable without affecting beam output.
The consistent H6024 fitment across the 2008-2017 model range indicates that no headlight housing or electrical interface changes were introduced during that production period that would affect bulb compatibility.
