The Buick Super headlight bulb size chart specifies high beam and low beam bulb options including H5001, H6024, and H6006 sizes for this vehicle model. The replacement chart covers 1950 through 1958 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6006 sealed beam unit is the most frequently specified bulb across these specifications, serving as both the high beam and low beam headlight on the Buick Super from 1950-1953. It is a 5x7-inch rectangular sealed beam unit rated at 12V and conforms to the ANSI standard for the US and Canada.
The H6024 is a 7-inch round sealed beam unit rated at 12V and built to the same ANSI standard. It appears as both the high beam and low beam specification for the 1954-1957 model years, making it the sole headlight type across those four years.
All four bulb types listed in these specifications 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 an internal bulb swap.
The 1958 Buick Super marks a departure from the single-unit headlight arrangement used in prior years. That year, the high beam and low beam positions use two distinct sealed beam types: the H5001 for the high beam and the H5006 for the low beam.
The H5001 is a 4-inch square sealed beam unit rated at 12V. Its square form factor is physically incompatible with the round or rectangular housings used in earlier model years, so it is not interchangeable with the H6006 or H6024 units.
The H5006 is a 5.75-inch round sealed beam unit rated at 12V. Although it shares a round profile with the H6024, the two differ in size and are not interchangeable despite their similar shape.
All bulb types in these specifications operate at 12V, which reflects the industry-wide transition from 6V to 12V electrical systems that took place in American vehicles during the early 1950s.
Because each sealed beam type carries a distinct ANSI designation, substituting one unit for another across different model years is not supported by these specifications, even where voltage ratings match.
