Additional Notes

All headlight bulb sizes listed for the Ford Country Squire across its full model range are sealed beam units, meaning the entire lens-and-filament assembly is replaced as one piece rather than a separate bulb being swapped within a housing.
Every sealed beam type in these specifications operates at 12V and conforms to ANSI standards recognized in both the United States and Canada.
The H4651 is a 4x6-inch rectangular sealed beam unit used as the high beam headlight on the Ford Country Squire for model years 1987-1991. Its low beam counterparts across those same years are not a single uniform type, with H4656 fitted to 1987, 1988, and 1991, and H4652 fitted to 1989 and 1990.
The H4652 is described as a variant of the H4651, and both share the same 4x6-inch rectangular sealed beam format. Despite this physical similarity, they carry distinct ANSI designations and are not listed interchangeably within these specifications.
The H5001, a 4-inch square sealed beam unit, served as the high beam headlight across model years 1958-1974, while the H5006, a 5.75-inch round sealed beam unit, covered the low beam function for the same span of years.
The 1956-1957 model years used the H6024, a 7-inch round sealed beam unit, for both high and low beam functions, making it the only type in these specifications where a single bulb designation covered both beam positions simultaneously.
The H6006, a 5x7-inch rectangular sealed beam unit, was used for both high and low beam positions on the 1950-1955 model years, also representing a single-type fitment across both beam functions.
The physical format of the headlight assemblies changed several times across the Country Squire's listed model range, moving from 5x7-inch rectangular units in the early 1950s, to 7-inch round units in 1956-1957, to 4-inch square and 5.75-inch round pairings through the 1960s and early 1970s, and finally to 4x6-inch rectangular units in the late 1980s and 1991. These format differences mean sealed beam units from one era are not physically interchangeable with those from another.
