Oldsmobile Super 88 Headlight Bulb Size

Oldsmobile Super 88 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 1951 through 1964 production years with corresponding bulb size specifications.

Additional Notes

The Oldsmobile Super 88 headlight specifications span the 1951-1964 model years and reference four distinct sealed beam unit types: H5001, H5006, H6024, and H6006. All four conform to ANSI standards applicable in the United States and Canada and operate on 12V electrical systems.
Sealed beam units, by design, house the filament, reflector, and lens within a single fused glass assembly. When a filament fails, the entire unit requires replacement rather than an internal bulb swap. This applies to all four types listed in the Super 88 specifications.
The H6024 is a 7-inch round sealed beam unit and serves as both the high beam and low beam source for the 1953-1957 model years. Its use across both functions in those years indicates a single-beam-per-housing headlight system, where separate housings handle each beam mode.
The H6006 is a 5x7-inch rectangular sealed beam unit and appears in both the high beam and low beam positions for the 1951-1952 Oldsmobile Super 88. Like the H6024, it functions as a dual-purpose unit across separate housings rather than a dual-filament design.
Beginning with the 1958 model year, the Super 88 transitions to separate unit types for high and low beams. The H5001, a 4-inch square sealed beam, covers the high beam position, while the H5006, a 5.75-inch round sealed beam, covers the low beam position. This split continues through 1964.
The H5001 and H5006 are physically distinct units with different form factors, making them non-interchangeable despite both being 12V ANSI-standard sealed beams. Installing the incorrect unit in either housing would result in a physical fitment mismatch.
The H6024 and H6006 units, while both round or near-rectangular sealed beams from earlier model years, differ in size and are likewise not interchangeable with each other or with the H5001 and H5006 units used in later years.
The shift from H6006 in 1951-1952 to H6024 in 1953-1957, and then to the split H5001/H5006 configuration from 1958 onward, reflects distinct headlight housing generations across the Super 88 production run, meaning replacement units must correspond precisely to the model year of the vehicle.
