Plymouth Savoy high beam and low beam headlight bulbs utilize H5001, H6024, and H6006 sizes, with the low beam configuration also incorporating H5006 bulb options across multiple generations. The replacement chart documents vehicle production years spanning 1953 to 1964 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 Plymouth Savoy headlight specifications span the 1953-1964 model years, covering both high beam and low beam positions across four distinct sealed beam bulb types: H5001, H5006, H6024, and H6006.
All four bulb types are ANSI-standardized sealed beam units rated at 12V. Because the lens, reflector, and filament are fused into a single assembly, the entire unit requires replacement rather than an internal bulb swap.
The H5001 is a 4-inch square sealed beam unit used exclusively in the high beam position on the Plymouth Savoy for the 1957-1964 model years. Its square form factor is specific to that dedicated high beam role in a quad-lamp headlight arrangement.
The H5006 is a 5.75-inch round sealed beam unit and serves as the low beam counterpart to the H5001, covering the same 1957-1964 range. The two units are not interchangeable despite sharing the same era, as they differ in both shape and beam function.
The H6024 is a 7-inch round sealed beam unit and appears in both the high beam and low beam positions for the 1956 model year only. Its single-year use reflects a transitional point in the Savoy's headlight configuration.
The H6006 is a 5x7-inch rectangular sealed beam unit used in both the high beam and low beam positions for the 1953-1955 model years. A single H6006 unit served both beam functions in a two-lamp headlight system during that period.
The shift from the H6006 rectangular unit to the H6024 round unit in 1956, and then to the separate H5001 and H5006 units from 1957 onward, reflects a progression from single-unit dual-function sealed beams to dedicated high and low beam assemblies.
Because the H5001 and H5006 are physically distinct in shape and size, substituting one for the other in the 1957-1964 Plymouth Savoy is not possible without altering the headlight housing.
