Ford Zodiac headlight bulbs utilized H6024 and H6006 sizes for both high and low beam applications, with these bulb designations representing the primary specifications for the model. The replacement chart covers vehicle production spanning 1955 to 1961, detailing bulb size requirements across the model's manufacturing period.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Zodiac headlight bulb specifications cover model years 1955-1961, with two distinct sealed beam unit types used across that span: the H6006 for 1955-1958 and the H6024 for 1959-1961.
Both the H6006 and H6024 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.
The H6024 is a 7-inch round sealed beam unit operating at 12V and conforming to ANSI standards recognized in both the United States and Canada. The Ford Zodiac MK II uses this unit for both high and low beam functions across 1959-1961.
The H6006 is a 5x7-inch rectangular sealed beam unit, also rated at 12V and built to the same ANSI standard. It serves both the high beam and low beam positions on the 1955-1958 Zodiac.
Because the H6006 and H6024 differ in physical shape, one unit is not a substitute for the other. The rectangular H6006 and the round H6024 occupy different housings and are not interchangeable between model year groups.
The high beam and low beam positions share the same bulb size within any given model year. A single sealed beam type covers both functions for each year listed in the specifications.
The ANSI designation on both units indicates a standardized specification governing the physical form and electrical interface, which means replacement units from different manufacturers conforming to the same ANSI code are generally compatible with the original housing.
