International S1654LP high beam and low beam headlight bulbs both use H6024 size. The replacement chart covers 1988 to 1989 vehicle production years with bulb specifications.
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 listed positions and years for the International S1654LP, appearing in both the high beam and low beam headlight applications for 1988-1989.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts. It conforms to ANSI standards recognized in both the United States and Canada.
As a sealed beam unit, the H6024 does not contain a separately replaceable bulb element. When the light source fails, the entire sealed beam assembly is replaced as a single unit.
The high beam and low beam positions on the International S1654LP share the same H6024 specification for 1988-1989, meaning the same sealed beam unit serves both functions across those positions.
