Chevrolet Corvair headlight bulbs utilize H5001 size for high beam and H5006 size for low beam applications. The replacement chart covers 1960 through 1969 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 Chevrolet Corvair uses the H5001 sealed beam unit for the high beam headlight position across all model years from 1960-1969.
The H5001 is a 4-inch square sealed beam unit operating at 12 volts, conforming to ANSI standards recognized in both the United States and Canada.
The low beam headlight position across the same 1960-1969 model range calls for the H5006 sealed beam unit.
The H5006 is a 5.75-inch round sealed beam unit, also rated at 12 volts and built to the same ANSI standard as the H5001.
Both the H5001 and H5006 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 H5001 and H5006 are not interchangeable with each other, as they differ in shape and physical size, with the high beam unit being square and the low beam unit being round.
