Oldsmobile Vista Cruiser headlight bulbs utilize H6024 and H5001 sizes for high beam applications, with H6024 and H5006 sizes for low beam configurations. The replacement chart covers 1964 through 1975 production 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 Vista Cruiser uses two distinct headlight configurations across its model years. The 1964-1973 model years rely on sealed beam units from the H5001 and H5006 family, while the 1974-1975 model years use the H6024 sealed beam unit for both high and low beam positions.
The H6024 is a 7-inch round sealed beam unit operating at 12V and conforming to ANSI standards recognized in both the United States and Canada. It serves as a dual-function unit, covering both the high beam and low beam positions in the 1974-1975 Vista Cruiser.
The H5001 is a 4-inch square sealed beam unit, also rated at 12V and built to the same ANSI standard. It fills the high beam position across the 1964-1972 model years, representing the longest-running bulb type in the Vista Cruiser's headlight specifications.
The H5006 is a 5.75-inch round sealed beam unit at 12V, again conforming to ANSI standards for the US and Canadian markets. It occupies the low beam position for the 1964-1972 model years, pairing with the H5001 in a four-headlight arrangement typical of that era.
All three bulb types, H6024, H5001, and H5006, are sealed beam units. In a sealed beam design, the reflector, lens, and filament are fused into a single glass housing, meaning the entire unit is replaced rather than an individual bulb element.
The 1964-1972 Vista Cruiser uses two different sealed beam sizes simultaneously, with the smaller 4-inch square H5001 handling high beam duties and the larger 5.75-inch round H5006 handling low beam duties. These two units are not interchangeable due to their differing physical formats and beam functions.
The shift to the H6024 in 1974-1975 consolidates both beam functions into a single sealed beam type. Despite this functional overlap, the H6024 is physically distinct from the H5001 and H5006 and is not a substitute for either of the earlier units.
All sealed beam types listed carry ANSI standardization, which means they conform to defined specifications for size, wattage, and beam pattern shared across manufacturers in the US and Canadian markets, allowing equivalent units from different producers to be used as replacements.
