The Ford B-7000 headlight bulb uses an H6054 size for both high beam and low beam applications. The replacement chart covers vehicle production spanning 1983 to 1987.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford B-7000 uses the H6054 bulb size for both the high beam and low beam headlight positions across the 1983-1987 model years.
The H6054 is a 5x7-inch rectangular sealed beam unit, meaning the lens, reflector, and filament are fused into a single assembly rather than a separate bulb housed within a reflector housing.
Because the H6054 is a sealed beam unit, the entire assembly is replaced when the light fails, not an individual bulb.
The H6054 operates at 12 volts and conforms to ANSI standards recognized in both the United States and Canada.
The shared H6054 specification across both the high beam and low beam positions indicates that the Ford B-7000 uses a dual-function sealed beam unit rather than separate assemblies for each lighting mode.
The rectangular form factor of the H6054 is not interchangeable with round sealed beam types such as the 5.75-inch or 7-inch circular units, as the mounting configurations differ.
