Chrysler Windsor Headlight Bulb Size

Chrysler Windsor headlight bulbs utilize H5001, H6024, and H6006 sizes for high beam applications, while low beam configurations employ H5006, H6024, and H6006 bulb sizes. The replacement chart covers 1950 through 1961 production years with corresponding bulb size specifications.

Additional Notes

The Chrysler Windsor uses three distinct sealed beam types across its high beam positions depending on model year: the H6006 rectangular unit covers 1950-1955, the H6024 round unit covers 1956-1957, and the H5001 square unit covers 1958-1961.
All four bulb types referenced in these specifications, the H5001, H5006, H6024, and H6006, are ANSI-standardized sealed beam units rated at 12 volts and certified for use in both the United States and Canada.
Sealed beam units integrate the filament, reflector, and lens into a single fused glass assembly. Because of this construction, the entire unit requires replacement rather than an internal bulb component.
The 1957-1956 Windsor uses the H6024, a 7-inch round sealed beam, for both high and low beam functions. This single-unit dual-beam design was a common configuration in mid-century American vehicles before quad headlight systems became widespread.
For 1958-1961, the Chrysler Windsor transitions to a split high/low beam system using two different sealed beam types: the H5001, a 4-inch square unit, handles high beam duty, while the H5006, a 5.75-inch round unit, handles low beam duty.
The H5001 and H5006 are not interchangeable despite both being used simultaneously on the 1958-1961 Windsor. They differ in physical form factor, with the H5001 being a 4-inch square unit and the H5006 being a 5.75-inch round unit, making cross-substitution physically impossible.
The H6006 is a 5x7-inch rectangular sealed beam unit used across the Windsor's high and low beam positions for 1950-1955. Its rectangular shape distinguishes it from the round and square units used in later model years.
The shift from the H6006 in 1955 to the H6024 in 1956 reflects the Windsor's transition from a rectangular sealed beam format to a 7-inch round sealed beam format, both of which remain ANSI-standardized 12-volt units.
