Chevrolet Kingswood high beam headlight bulbs use H5001 size while low beam headlight bulbs use H5006 size. The replacement chart covers 1959 through 1972 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 Chevrolet Kingswood uses the H5001 bulb type for high beam headlights across all listed model years. The H5001 is an ANSI-standard sealed beam unit recognized in both the United States and Canada, operating at 12 volts. It is a 4-inch square sealed beam, meaning the entire unit is replaced rather than an internal filament or capsule.
The low beam headlight position across all listed model years calls for the H5006, another ANSI-standard 12-volt sealed beam unit. The H5006 is a 5.75-inch round sealed beam, physically distinct from the square H5001 used in the high beam position.
Because both the H5001 and H5006 are sealed beam units, the lens, reflector, and filament are fused into a single assembly. Replacement involves removing the entire headlight unit rather than accessing an internal bulb.
The H5001 and H5006 are not interchangeable with each other. Their differing shapes, one square and one round, along with their distinct ANSI designations, mean each is specific to its respective beam position.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating a standardized specification that allows units from multiple manufacturers to serve as direct replacements provided they carry the correct ANSI designation.
The Chevrolet Kingswood carries the H5001 high beam specification across the 1959-1961 and 1969-1972 model years, and the H5006 low beam specification across those same years, with no variation in bulb type between any of the listed years for either position.
