The Ford F-3 high beam and low beam headlight bulbs both utilize the H6006 size. The replacement chart covers 1950 to 1952 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford F-3 uses the H6006 bulb size across both the high beam and low beam headlight positions for the 1950-1952 model years.
The H6006 is an ANSI-standard sealed beam unit recognized in the United States and Canada, operating at 12 volts.
The H6006 unit follows a 5x7-inch rectangular form factor, which was a regulated sealed beam format standardized under ANSI specifications for North American vehicles of that era.
As a sealed beam unit, the H6006 is not serviceable at the bulb level. When the light source fails, the entire lens, reflector, and filament assembly is replaced as one unit.
Because the Ford F-3 uses the same H6006 specification for both high and low beam positions, the vehicle relies on the sealed beam unit itself to produce both beam patterns, rather than separate bulbs assigned to each function.
