The Ford Skyliner high beam and low beam headlight bulb sizes include H5001, H6024, and H6006 options, with the low beam bulb also utilizing H5006 in certain configurations. The replacement chart covers 1954 through 1959 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 Skyliner headlight specifications across 1954-1959 rely exclusively on sealed beam units, a lamp format in which the reflector, lens, and filament are fused into a single assembly. When the filament fails, the entire unit requires replacement rather than an internal bulb swap.
All four sealed beam types listed for the Skyliner, H5001, H6024, H6006, and H5006, operate at 12 volts and conform to ANSI standards recognized in both the United States and Canada.
The H6006 is a 5x7-inch rectangular sealed beam unit used for both high and low beam functions on the 1954-1955 Ford Skyliner. Its rectangular form factor was a common format in mid-1950s American vehicle lighting.
The H6024 is a 7-inch round sealed beam unit that serves both high and low beam positions on the 1956-1957 Skyliner. Because a single unit type covers both functions in those years, the high and low beam outputs are determined by the internal filament configuration of the H6024 itself.
The 1958-1959 Skyliner uses separate unit types for high and low beams, with the H5001 assigned to high beam and the H5006 to low beam. This split reflects a four-headlight system, which became federally permitted in the United States in 1957 and was adopted by many manufacturers for the 1958 model year.
The H5001 is a 4-inch square sealed beam unit used exclusively for the high beam position in 1958-1959. Its square housing is specific to the outboard or inboard high-beam position in quad-headlight arrangements of that period.
The H5006 is a 5.75-inch round sealed beam unit assigned to the low beam position in 1958-1959. Its round format and larger face relative to the H5001 reflect the distinct optical requirements of low beam projection.
Because each sealed beam type has a physically distinct housing shape and size, H5001, H6024, H6006, and H5006 units are not interchangeable with one another, and substitution across model years is not supported by these specifications.
