Ford Capri high beam headlight bulbs use H5001 size while low beam headlight bulbs use H5006 size. The replacement chart covers 1962 to 1964 vehicle production years 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 Capri uses two distinct sealed beam units across its 1962-1964 model years: the H5001 for high beam and the H5006 for low beam.
Both the H5001 and H5006 are sealed beam units, meaning the lens, reflector, and filament are fused into a single assembly. When the filament fails, the entire unit requires replacement rather than an internal bulb swap.
The H5001 is a 4-inch square sealed beam unit operating at 12V, conforming to ANSI standards recognized in both the United States and Canada.
The H5006 is a 5.75-inch round sealed beam unit also rated at 12V and held to the same ANSI standard as the H5001.
The square profile of the H5001 and the round profile of the H5006 make the two units physically incompatible with each other's housings, so the high beam and low beam positions are not interchangeable.
The ANSI standardization of both units means physically compatible replacements from multiple manufacturers may exist, provided they conform to the same H5001 or H5006 designations respectively.
The 12V operating voltage of both units is consistent with the 12-volt electrical systems standard in automotive applications of that era.
