The International COF5870 Paystar headlight bulb uses H6024 size for both high beam and low beam applications. The replacement chart covers 1985 to 1988 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 H6024 is the sole bulb type listed across all headlight positions in the International COF5870 Paystar specifications, appearing in both high beam and low beam applications for the 1985-1988 model years.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts, conforming to ANSI standards recognized in both the United States and Canada.
As a sealed beam unit, the H6024 is not a replaceable bulb in the conventional sense. When the light source fails, the entire sealed unit requires replacement rather than an internal filament or capsule.
The identical H6024 specification for both high beam and low beam positions indicates that a single unit type serves dual functions, a design characteristic common to sealed beam headlight systems of that era where switching between beams is handled internally by separate filaments within the same sealed assembly.
The ANSI standardization of the H6024 means the unit conforms to fixed physical and electrical parameters, which generally allows interchangeability between manufacturers producing bulbs to the same ANSI designation.
