Plymouth Fury II 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 bulb size specifications across 1965 to 1974 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Fury II uses the H5001 sealed beam unit for high beam headlights across all model years from 1965-1974.
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.
The H5006 sealed beam unit serves the low beam headlight position on the Fury II across the same 1965-1974 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, it 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 are not interchangeable with each other despite sharing the same voltage rating and standards body.
Because both sealed beam types are ANSI-standardized, replacement units from any manufacturer meeting that specification are compatible with the Plymouth Fury II, provided the correct type (H5001 or H5006) is matched to the correct headlight position.
