Ford B-600 Headlight Bulb Size

The Ford B-600 headlight bulb uses H6054 and 9007 size specifications for both high and low beam applications. A replacement chart documents bulb size data spanning 1980 to 1994 production years.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V. Unlike replaceable bulb designs, the entire sealed beam assembly is replaced as a single unit when it fails. It conforms to ANSI standards recognized in both the United States and Canada.
The 9007 is a dual-filament halogen bulb with a PX29t base, rated at 12V with a wattage of 65W on high beam and 55W on low beam. Its dual-filament construction allows a single bulb to serve both high and low beam functions within a composite headlamp housing. It also conforms to ANSI standards recognized in both the United States and Canada.
The Ford B-600 used the H6054 sealed beam as the sole headlight bulb for both high and low beam functions across the 1980-1992 model years, covering a span of thirteen consecutive years without variation.
For the 1993-1994 model years, the Ford B-600 introduced a headlamp system split, where vehicles fitted with two rectangular headlamps retained the H6054 sealed beam, while those fitted with composite headlamps used the 9007 halogen bulb instead.
Because the H6054 and 9007 are not interchangeable, the headlamp housing type on 1993-1994 Ford B-600 vehicles is a determining factor in which bulb size applies. Rectangular and composite housings require entirely different bulb formats and cannot accept the same unit.
The H6054 sealed beam serves both high and low beam roles within a single unit, a function achieved through internal filament arrangement rather than through separate bulbs, which is the same functional outcome as the 9007's dual-filament design but through a fundamentally different construction.
