The Ford F-700 high beam and low beam headlight bulb sizes include H6054, 9007, and H6024 specifications. A replacement chart documents bulb size data spanning from 1970 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6054 is the most widely specified bulb across the Ford F-700 headlight data, covering both high beam and low beam positions for the majority of model years in the specifications. It is a 5x7-inch rectangular sealed beam unit operating at 12V, built to ANSI standards for the US and Canadian markets. Because it is a sealed beam design, the entire unit is replaced rather than an internal filament or capsule.
The H6024 appears in the Ford F-700 specifications for 1971, 1976, and 1978 across both high beam and low beam positions. It is a 7-inch round sealed beam unit, also rated at 12V and held to the same ANSI standard as the H6054. Like the H6054, it is a full-unit replacement rather than a serviceable bulb.
The H6054 and H6024 are not interchangeable. One is a 5x7-inch rectangular unit and the other is a 7-inch round unit, meaning the housing shape and mounting configuration differ between them. Installing the wrong sealed beam type would result in an improper fit.
For 1993-1998, the Ford F-700 specifications list two distinct bulb sizes depending on headlamp configuration. Vehicles fitted with two rectangular headlamps use the H6054, while those fitted with composite headlamps use the 9007. The correct bulb is determined by which headlamp system the vehicle carries.
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. A single 9007 bulb serves both the high beam and low beam functions within a composite headlamp assembly, unlike the sealed beam units which are dedicated per function or per housing.
Because the 9007 uses a PX29t base and the H6054 is a sealed beam unit with an entirely different mounting format, the two types are not interchangeable regardless of voltage compatibility. Composite headlamp housings are designed specifically for the 9007 capsule and cannot accept a sealed beam unit.
The H6054 serves both the high beam and low beam positions simultaneously in a sealed beam configuration, meaning a single unit handles both functions through its internal dual-filament construction. This is consistent across all model years in the specifications where the H6054 is listed under both sub-parts.
