Ford Zephyr headlight bulbs utilized H6024 and H6006 sizes for both high and low beam applications, with the bulb specifications varying across the model's production run. The replacement chart covers 1952 through 1961, detailing bulb size requirements for each year within that range.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Zephyr high beam and low beam headlights share the same bulb type across all listed model years, meaning a single sealed beam unit serves both functions depending on the year.
The H6006 is a 5x7-inch rectangular sealed beam unit operating at 12V and conforming to ANSI standards recognized in the United States and Canada. It was used on the Ford Zephyr from 1952-1958 for both high and low beam headlights.
The H6024 is a 7-inch round sealed beam unit operating at 12V and also conforming to ANSI standards recognized in the United States and Canada. It was used on the 1959-1961 Zephyr MK II for both high and low beam headlights.
Both the H6006 and H6024 are sealed beam units, meaning the lens, reflector, and filament are fused into a single assembly. When a filament fails, the entire unit requires replacement rather than an individual bulb.
The H6006 and H6024 are not interchangeable. The H6006 is rectangular at 5x7 inches while the H6024 is a 7-inch round unit, and their housing mountings differ accordingly.
The transition from the H6006 to the H6024 coincides with the introduction of the MK II designation, which applies to the 1959-1961 model years in these specifications.
