The Jeep CJ6A headlight bulb uses an H6024 size for both high beam and low beam applications. The replacement chart covers vehicle production years spanning 1966 to 1968.
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 positions and years in the Jeep CJ6A headlight specifications, covering both high beam and low beam functions for the 1966-1968 model years.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts, conforming to ANSI standards applicable in 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 dual roles in the CJ6A, functioning as both the high beam and low beam headlight, which indicates a two-headlight system rather than a four-headlight configuration with separate dedicated units per function.
Because the H6024 is a sealed beam type, fitment is governed by the physical housing size and electrical rating rather than a bulb socket standard, making cross-compatibility dependent on matching the 7-inch round form factor and 12-volt rating.
