The Jeep CJ5A headlight bulb uses an H6024 size for both high beam and low beam applications. The replacement chart covers vehicle production 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 CJ5A 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.
Unlike bulb-and-housing systems, the sealed beam design integrates the filament, reflector, and lens into a single glass unit, meaning the entire assembly is replaced rather than an internal bulb.
The H6024 serves dual duty in the CJ5A, fulfilling both the high beam and low beam headlight positions, which indicates the vehicle uses a two-headlight system where each sealed beam unit contains separate filaments for each function.
Because the H6024 is a standardized ANSI unit, it is interchangeable across any vehicle requiring that specification, provided the mounting hardware and wiring connector are compatible.
