The Ford F-1 high beam and low beam headlight bulbs both utilize the H6006 size. The replacement chart covers 1950 to 1952 vehicle 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-1 uses the H6006 bulb type across all listed model years (1950-1952) for both high beam and low beam headlight positions.
The H6006 is an ANSI-standard sealed beam unit recognized in the United States and Canada, operating at 12 volts.
A sealed beam unit integrates the filament, reflector, and lens into a single non-serviceable assembly, meaning the entire unit is replaced rather than an internal bulb.
The H6006 follows a 5x7-inch rectangular form factor, which is a standardized size shared across many vehicle applications of that era, making cross-brand physical fitment possible in some cases.
Because the Ford F-1 (1950-1952) uses the same H6006 unit for both high and low beam functions, the headlight assembly relies on a dual-filament sealed beam design rather than separate housings for each beam type.
The ANSI standardization of the H6006 means that any compliant unit bearing that designation should meet the same electrical and optical specifications, regardless of manufacturer.
