Ford B-700 headlight bulbs utilize H6054 and 9007 sizes for both high and low beam applications. The replacement chart covers vehicle production spanning 1980 to 1994 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 B-700 uses the H6054 bulb for both high beam and low beam headlights across the 1980-1992 model years, making it the dominant fitment across the specification range.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V. It conforms to ANSI standards applicable in the United States and Canada, and the entire unit is replaced rather than an internal filament or capsule.
For the 1993-1994 model years, the Ford B-700 fitment splits into two distinct types depending on headlamp configuration: the H6054 applies to vehicles with two rectangular headlamps, while the 9007 applies to vehicles with composite headlamps.
The 9007 is a dual-filament halogen bulb with a PX29t base, rated at 12V with 65W on high beam and 55W on low beam. It also conforms to ANSI standards for the United States and Canada.
Because the H6054 is a sealed beam unit and the 9007 is a replaceable halogen capsule, the two bulb types are not interchangeable despite serving the same high beam and low beam functions in the 1993-1994 model years.
The dual-filament design of the 9007 means a single bulb serves both the high beam and low beam positions in composite headlamp assemblies, whereas the H6054 sealed beam handles both functions within one self-contained unit in rectangular headlamp assemblies.
