The Jeep J-3700 headlight bulb uses H6024 size for both high beam and low beam applications. The replacement chart covers vehicle production spanning 1965 to 1970.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jeep J-3700 uses the H6024 bulb size across all listed model years, 1965-1970, for both high beam and low beam headlight positions.
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 non-serviceable assembly, meaning the entire unit is replaced rather than an internal bulb.
The H6024 is a 7-inch round sealed beam format, a configuration that was standardized for North American vehicles and shared across many makes during this period.
Because the Jeep J-3700 uses the same H6024 unit for both the high beam and low beam positions, the sealed beam itself handles both lighting functions within one assembly rather than relying on separate single-function units.
The shared H6024 specification across all six listed model years means no year-specific fitment variation exists within the 1965-1970 range for this vehicle.
