Oldsmobile Deluxe 88 headlight bulbs utilized H6024 and H6006 sizes for both high and low beam applications. The replacement chart covers 1951 through 1956 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Oldsmobile Deluxe 88 used two distinct sealed beam headlight units across its 1951-1956 model years: the H6006 for 1951-1952 and the H6024 for 1953-1956.
The H6024 is a 7-inch round sealed beam unit operating at 12V and conforming to ANSI standards applicable in both the United States and Canada.
The H6006 is a 5x7-inch rectangular sealed beam unit, also rated at 12V and built to the same ANSI standard covering the US and Canadian markets.
Both the H6024 and H6006 are sealed beam units, meaning the lens, reflector, and filament are fused into a single assembly, and the entire unit is replaced rather than an internal bulb.
On the Oldsmobile Deluxe 88, the H6024 and H6006 each serve both the high beam and low beam functions within a single sealed unit, as the specifications list the same bulb size for both sub-parts in every model year.
The H6024 and H6006 differ in physical form factor, with the H6024 being round and the H6006 being rectangular, making the two units non-interchangeable despite sharing the same voltage rating and ANSI compliance.
