Plymouth Fury Headlight Bulb Size

Plymouth Fury high beam and low beam headlight bulbs utilize 3 distinct sizes: H4651, H6024, H5001 for high beam applications and H4652, H6024, H5006 for low beam applications, with each bulb size corresponding to specific vehicle configurations. The replacement chart covers 1956 through 1978 production years with corresponding bulb size specifications for each model year.

Additional Notes

The H5001 is the most frequently specified bulb across the Plymouth Fury's headlight history, serving as the high beam unit for model years 1957-1974. It is a 4-inch square sealed beam unit operating at 12V and conforming to ANSI standards recognized in both the United States and Canada.
The H5006 mirrors the H5001's span of use on the low beam side, covering model years 1957-1974 for the Plymouth Fury. It is a 5.75-inch round sealed beam unit, also rated at 12V and built to the same ANSI standard framework.
All bulb types listed for the Plymouth Fury 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.
For 1977-1978, the Plymouth Fury uses two distinct sealed beam types within the same headlight system: the H4651 for high beam and the H4652 for low beam. Both are 4x6-inch rectangular units, with the H4652 classified as a variant of the H4651, indicating close but non-interchangeable specifications between the two functions.
The H6024, a 7-inch round sealed beam unit, was specified for both high and low beam positions in 1975-1976 and again in 1956. Its use across both beam positions in those years indicates a single-unit headlight configuration rather than a split high/low beam system.
The shift from H5001 and H5006 units to H6024 units between 1974 and 1975 represents a change in both the physical form factor and the beam configuration, moving from separate square and round units for each beam function to a single round unit serving both roles.
The subsequent transition from H6024 units in 1975-1976 to the H4651 and H4652 rectangular units in 1977-1978 reflects a further change in headlight geometry, with the 4x6-inch rectangular format replacing the 7-inch round format and reintroducing dedicated high and low beam units.
All sealed beam types listed carry ANSI standardization applicable to both the United States and Canada, meaning physically compatible replacement units sourced from either market conform to the same regulated output and fitment criteria.
