The Ford C800 high beam and low beam headlight bulb sizes utilize H6054 and H6024 bulb configurations. The replacement chart covers vehicle production spanning 1980 to 1989 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 Ford C800 headlight bulb specifications cover the 1980-1989 model years, with the H6024 being the sole bulb type used across both high beam and low beam positions for the 1980-1986 model years.
The H6024 is a 7-inch round sealed beam unit built to ANSI standards applicable in both the United States and Canada, operating at 12 volts. As a sealed beam design, the entire unit is replaced rather than an internal filament or capsule.
The H6054 is a 5x7-inch rectangular sealed beam unit, also conforming to ANSI standards for the US and Canadian markets and operating at 12 volts. Like the H6024, it is replaced as a complete unit.
For the 1987-1989 model years, the Ford C800 headlight bulb size is determined by the headlamp configuration present on the vehicle. Units equipped with two rectangular headlamps use the H6054, while units equipped with two round headlamps use the H6024.
Both the H6054 and H6024 serve dual roles in the Ford C800, covering both high beam and low beam functions within their respective headlamp configurations. Sealed beam units of this type typically integrate both beam functions into a single replaceable assembly.
The H6054 and H6024 are not interchangeable with one another. Their physical forms differ, with one being rectangular and the other round, making correct identification of the headlamp configuration a necessary step before sourcing a replacement unit.
