American Motors Javelin high beam and low beam headlight bulbs both utilize the H6024 size. The replacement chart covers 1968 to 1974 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The American Motors Javelin uses the H6024 bulb size across both high beam and low beam headlight positions for the full 1968-1974 production span.
The H6024 is an ANSI-standard 7-inch round sealed beam unit rated at 12 volts, used in both the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single glass assembly, meaning the entire unit is replaced rather than an internal bulb.
Because the H6024 serves both the high beam and low beam positions on the Javelin, a single bulb type covers all headlight replacement needs across the vehicle.
The H6024 sealed beam format was a widely adopted standard in North American automotive lighting during this era, making the unit broadly available across multiple suppliers.
The 7-inch round form factor of the H6024 is a standardized size, meaning units from different manufacturers sharing that designation are generally interchangeable within the same ANSI specification.
