The Jeep J-4500 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 1970 to 1973.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jeep J-4500 uses the H6024 bulb size for both high beam and low beam headlights across the 1970-1973 model years.
The H6024 is an ANSI-standard sealed beam unit recognized in both the United States and Canada, operating at 12 volts.
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.
The H6024 follows a 7-inch round form factor, which was a standardized headlight format widely adopted in North American vehicle manufacturing during this era.
Because the Jeep J-4500 uses the same H6024 specification for both high and low beam positions, both headlight functions are served by a single bulb type, though each position still requires its own physical unit.
The shared H6024 fitment across all four model years and both beam positions means no year-specific or beam-position-specific variation exists within this vehicle's headlight system.
