Plymouth Sport Wagon high beam headlight bulbs measure H5001 in size, while low beam headlight bulbs measure H5006, with both bulb sizes specified for the vehicle model. The replacement chart contains specifications covering 1960 to 1961 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H5001 is a 4-inch square sealed beam unit operating at 12V and conforming to ANSI standards recognized in both the United States and Canada. Rather than housing a replaceable internal bulb, the entire sealed beam assembly is the serviceable component.
The H5006 is a 5.75-inch round sealed beam unit, also rated at 12V and built to the same ANSI standard. Like the H5001, it functions as a single replaceable assembly rather than a bulb-within-housing design.
The Plymouth Sport Wagon uses the H5001 for high beam and the H5006 for low beam across the 1960-1961 model years, meaning both sealed beam types are required for a complete headlight system on these vehicles.
Because the H5001 and H5006 differ in shape and size, the two units are not interchangeable with each other. The square format of the H5001 and the round format of the H5006 correspond to distinct mounting positions within the headlight system.
The ANSI designation on both units indicates conformance to a standardized specification, which historically allowed sealed beam headlights of the same type designation to be sourced from multiple manufacturers while remaining physically and electrically compatible.
