The Jeep J-3800 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1965 to 1971.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jeep J-3800 uses the H6024 bulb size across both the high beam and low beam headlight positions for the 1965-1971 model years.
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 filament fails in a sealed beam unit such as the H6024, the entire unit is replaced rather than an individual 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 same H6024 unit is specified for both the high beam and low beam positions on the Jeep J-3800, the vehicle uses a dual-headlight configuration where each sealed beam assembly serves a single dedicated function rather than a single unit handling both beams.
