Ford Galaxie 500 headlight bulbs include H5001 size for high beam and H5006 size for low beam applications. The replacement chart covers vehicle production spanning 1962 to 1974 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 Galaxie 500 uses the H5001 sealed beam unit for high beam headlights across all listed model years, spanning 1962-1974.
The H5001 is a 4-inch square sealed beam unit operating at 12V. It conforms to ANSI standards recognized in both the United States and Canada.
The low beam headlight position on the Galaxie 500 uses the H5006 sealed beam unit across the same 1962-1974 model year range.
The H5006 is a 5.75-inch round sealed beam unit, also rated at 12V and built to the same ANSI standard as the H5001.
Both the H5001 and H5006 are sealed beam units, meaning the lens, reflector, and filament are fused into a single assembly. When a filament fails, the entire unit requires replacement rather than an internal bulb swap.
The H5001 and H5006 differ in shape and size, with the high beam unit being square and the low beam unit being round. These two types are not interchangeable with each other.
