The Jeep J-4600 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1970 to 1973 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 an ANSI-standardized sealed beam unit used in both the high beam and low beam headlight positions of the Jeep J-4600 across the 1970-1973 model years.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts. Unlike bulb-based headlights, the entire sealed beam assembly is replaced as a single unit when the light fails.
The H6024 carries ANSI standardization recognized in both the United States and Canada, meaning the unit conforms to a defined physical and electrical specification shared across compliant vehicles of the era.
Because the Jeep J-4600 uses the same H6024 unit for both high beam and low beam functions, the vehicle does not use separate bulbs for each lighting mode. Both functions are handled within the sealed beam assembly itself.
The identical H6024 fitment across all four model years and both headlight positions means no year-specific or position-specific variation exists within this application range.
