Lincoln Premier high beam and low beam headlight bulbs utilize H5001, H6024, and H5006 sizes depending on beam type and model configuration. Replacement chart data spans 1956 to 1960 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 Lincoln Premier uses three distinct sealed beam unit types across its 1956-1960 model years: H5001, H5006, and H6024. All three conform to ANSI standards recognized in both the United States and Canada, and all operate on 12V electrical systems.
The H6024 is a 7-inch round sealed beam unit. The Lincoln Premier (1956-1957) uses this type for both high beam and low beam headlight positions, meaning a single unit design serves both functions in those model years.
The H5001 is a 4-inch square sealed beam unit used for the high beam headlight position on the 1958-1960 Premier. The square form factor distinguishes it from the round units used in earlier model years.
The H5006 is a 5.75-inch round sealed beam unit assigned to the low beam headlight position on the 1958-1960 Premier. Its round form factor differs from the square H5001 used alongside it for high beam in those same years.
All three bulb types 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 1958-1960 Premier uses separate unit types for high beam and low beam positions, H5001 and H5006 respectively. These two units are not interchangeable due to differing shapes and sizes.
The H6024 used on the 1956-1957 Premier is physically larger than both the H5001 and H5006 units used on later model years. Substituting units across these generations would not produce a correct fitment.
