The Jeep CJ3 headlight bulb uses the H6024 size for both high beam and low beam functions. The replacement chart covers vehicle production spanning 1959 to 1966.
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 Jeep CJ3 specifications, covering both high beam and low beam functions for the 1959-1966 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.
A sealed beam unit integrates the filament, reflector, and lens into a single fused glass assembly, meaning the entire unit is replaced rather than an internal bulb component.
The H6024 serves both the high beam and low beam positions in the Jeep CJ3, indicating that each headlight housing uses a single sealed beam unit capable of handling both functions through separate filaments within the same assembly.
Because the H6024 follows an ANSI standardized specification, physically compatible replacements from multiple manufacturers are generally interchangeable, provided they conform to the same standard.
