American Motors Classic high beam headlight bulbs measure H5001 in size, while low beam headlight bulbs measure H5006 in size. The replacement chart covers vehicle production spanning 1961 to 1966 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 American Motors Classic uses the H5001 sealed beam unit for high beam headlights across all model years from 1961-1966.
The H5001 is a 4-inch square sealed beam unit operating at 12V. It conforms to ANSI standards recognized in both the United States and Canada. The entire unit is replaced when the light fails, as the bulb is not a separate serviceable component.
Low beam headlights on the American Motors Classic use the H5006 sealed beam unit across the same 1961-1966 model year span.
The H5006 is a 5.75-inch round sealed beam unit, also rated at 12V and built to the same ANSI standard as the H5001. Like the H5001, the H5006 is replaced as a complete unit rather than as an individual bulb.
The H5001 and H5006 are physically distinct units. The H5001 is square while the H5006 is round, and the two differ in size, making them non-interchangeable between the high beam and low beam positions.
