The Ford F-7000 headlight bulb specifications include H6054 and H6024 sizes for both high and low beam applications, with bulb compatibility data organized by vehicle production year. The replacement chart covers the 1970 to 1987 model range and documents headlight bulb size requirements across this 18-year span.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6054 is the dominant headlight unit across the Ford F-7000 model range, appearing in both high beam and low beam positions for the 1971-1975 and 1977-1987 model years.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V and built to ANSI standards recognized in both the United States and Canada. Because it is a sealed beam design, the entire unit is replaced rather than an internal filament or bulb.
The H6024 is a 7-inch round sealed beam unit, also rated at 12V and conforming to the same ANSI standards. Like the H6054, it is a sealed beam assembly, meaning the whole unit is replaced upon failure.
The Ford F-7000 used the H6024 unit in both the high beam and low beam positions for the 1970 and 1976 model years, while all surrounding years used the H6054 rectangular unit instead.
Because the H6054 and H6024 differ in shape, a rectangular unit cannot be substituted for a round one without modification to the headlight housing, and vice versa. The 1970 and 1976 model years therefore require a different replacement unit than all other years in this specification range.
Both the H6054 and H6024 share the same 12V operating voltage and the same sealed beam construction principle, but their physical form factors are not interchangeable due to the difference between a rectangular and a round housing.
