Chevrolet Del Ray headlight bulbs utilize H5001 and H6024 sizes for high beam applications, with H5006 and H6024 sizes for low beam functions, representing the bulb specifications across this model line. The replacement chart documents bulb size data spanning 1957 to 1958 vehicle production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Del Ray uses three distinct sealed beam unit types across its headlight positions: H5001, H5006, and H6024, all of which conform to ANSI standards recognized in both the United States and Canada.
All three sealed beam types operate on a 12V electrical system, meaning they are compatible with the standard 12-volt automotive electrical architecture used in both model years covered by these specifications.
Sealed beam units are self-contained assemblies in which the lens, reflector, and filament are fused into a single unit. None of the three types listed accept a replaceable bulb; the entire assembly requires replacement when the unit fails.
The 1957 Chevrolet Del Ray uses the H6024, a 7-inch round sealed beam, for both the high beam and low beam positions. A single unit type serves both functions in that model year.
The 1958 model splits headlight duties between two different sealed beam types: the H5001 for the high beam and the H5006 for the low beam. These two units are not interchangeable with each other.
The H5001 is a 4-inch square sealed beam unit, while the H5006 is a 5.75-inch round unit. The difference in shape and size means substituting one for the other in the 1958 fitment is not possible.
The H6024 used in the 1957 model is physically larger than either unit found in the 1958 model, at 7 inches round, and is likewise not interchangeable with the H5001 or H5006 despite sharing the same 12V rating.
