The Jeep J-3500 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1965 to 1970 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 Jeep J-3500 uses the H6024 bulb size across all listed model years, 1965-1970, for both high beam and low beam headlight positions.
The H6024 is a 7-inch round sealed beam unit, meaning the lens, reflector, and filament are fused into a single assembly rather than housing a separate replaceable bulb inside.
When a sealed beam unit fails, the entire unit is replaced rather than an individual filament or bulb component.
The H6024 operates on a 12-volt electrical system and conforms to ANSI standards recognized in both the United States and Canada.
Because the J-3500 uses the same H6024 unit for both the high beam and low beam positions, a single part type serves the full headlight system across all six listed model years.
The 7-inch round form factor of the H6024 was a standardized size in North American automotive lighting, which means units from different manufacturers sharing that specification are generally interchangeable within the same socket and mounting configuration.
