Chevrolet Sedan Delivery Headlight Bulb Size

Chevrolet Sedan Delivery headlight bulbs utilize H5001, H6024, and H6006 sizes for high beam applications, with H5006, H6024, and H6006 sizes for low beam configurations. The replacement chart covers 1950 to 1960 production years with corresponding bulb size specifications.

Additional Notes

The Chevrolet Sedan Delivery uses three distinct sealed beam headlight types across its 1950-1960 model range: H6006, H6024, H5001, and H5006. All four conform to ANSI standards recognized in both the United States and Canada and operate on 12V electrical systems.
The H6006 is a 5x7-inch rectangular sealed beam unit fitted to the 1950-1955 model years for both high and low beam functions. Its rectangular form factor was a common format in American automotive lighting during that period.
For 1956-1957, both the high beam and low beam positions use the H6024, a 7-inch round sealed beam unit. The shared bulb type across both beam functions in those years means a single unit type serves the entire headlight assembly.
The 1958-1960 model years introduced a split-type headlight arrangement, with the H5001 serving the high beam and the H5006 serving the low beam. This reflects a dual-headlight system, where each function is handled by a separate, dedicated sealed beam unit.
The H5001 is a 4-inch square sealed beam unit, while the H5006 is a 5.75-inch round sealed beam unit. These two types are not interchangeable due to their differing physical forms, and installing one in place of the other is not possible without modification to the housing.
All four bulb types are sealed beam units, meaning the lens, reflector, and filament are fused into a single assembly. When the filament fails, the entire unit requires replacement rather than just an internal bulb.
The H6006 and H6024 units each serve dual beam roles in their respective years, functioning as both high and low beam within a single sealed unit. By contrast, the H5001 and H5006 each serve only one beam function, consistent with a four-headlight system design.
Because the Sedan Delivery transitioned through three different headlight configurations across its production span, substituting a unit from one era's specification into another year's housing is not supported by these fitment records.
