Additional Notes

The Dodge Coronet headlight specifications span model years 1950 through 1976, covering four distinct sealed beam bulb types across both high and low beam positions: H6024, H5001, H6006, and H5006.
All four bulb types are ANSI-standardized sealed beam units rated at 12V. Each is a self-contained assembly in which the lens, reflector, and filament form a single unit, meaning the entire assembly is replaced rather than an internal bulb.
The H6006 is a 5x7-inch rectangular sealed beam unit. It serves as both the high and low beam bulb for the Dodge Coronet across model years 1950-1955, making it the earliest bulb type recorded in these specifications.
The H6024 is a 7-inch round sealed beam unit. It appears as both the high and low beam bulb for the 1956 and 1975-1976 Coronet, and its round form factor distinguishes it from the rectangular H6006 it replaced in 1956 and the square H5001 used in later years.
The H5001 is a 4-inch square sealed beam unit used exclusively for the high beam position on the Coronet from 1957-1959 and again from 1965-1974. Its square form factor is a defining physical characteristic that sets it apart from the round and rectangular units used in other positions and years.
The H5006 is a 5.75-inch round sealed beam unit assigned exclusively to the low beam position on the Coronet from 1957-1959 and 1965-1974. During those same years, the high beam uses the physically smaller and differently shaped H5001, meaning the two beam positions are not interchangeable.
The pairing of H5001 (high beam) and H5006 (low beam) across 1957-1959 and 1965-1974 reflects a dual-headlight system in which each beam function uses a physically distinct sealed beam unit. Substituting one for the other would be incorrect, as the two types differ in both shape and size.
The 1975-1976 Coronet uses the H6024 for both high and low beam positions, making it the only configuration in these specifications where a single bulb type serves both functions simultaneously.
