The Jeep J10 headlight bulb uses H6054 and H6024 sizes for both high and low beam applications. The replacement chart covers vehicle production years spanning 1974 to 1988 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6054 and H6024 are the two sealed beam types specified for the Jeep J10 across its full model range. Both conform to ANSI standards recognized in the United States and Canada, and both operate at 12 volts.
The H6054 is a 5x7-inch rectangular sealed beam unit. Because the light source is fused with the reflector and lens into a single assembly, the entire unit requires replacement rather than an internal bulb swap.
The H6024 follows the same sealed beam construction principle but uses a 7-inch round form factor instead of a rectangular one. It is likewise a complete replacement unit.
The Jeep J10 used the H6054 for both high beam and low beam positions during the 1979-1988 model years. A single bulb type serving both functions in this way is characteristic of a dual-filament sealed beam design.
For the 1974-1978 model years, the J10 used the H6024 round sealed beam for both high beam and low beam positions, indicating a different headlight housing configuration compared to later production years.
The rectangular H6054 and the round H6024 are not interchangeable. Their differing shapes and mounting configurations correspond to distinct headlight housings, meaning a unit from the 1979-1988 specification cannot be substituted into a 1974-1978 housing, or vice versa.
The transition from the H6024 to the H6054 occurred between the 1978 and 1979 model years, representing a change in headlight form factor across both beam positions simultaneously.
