Ford Crestline high beam and low beam headlight bulbs both utilize the H6006 bulb size. The replacement chart covers vehicle production spanning 1950 to 1954.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6006 is the sole bulb type listed across all headlight positions in the Ford Crestline specifications, covering both high beam and low beam functions for the 1950-1954 model years.
The H6006 is a 5x7-inch rectangular sealed beam unit operating at 12 volts, standardized under ANSI specifications for use in the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single non-serviceable assembly, meaning the entire unit requires replacement rather than an internal bulb component.
The H6006 serves dual fitment in the Ford Crestline, covering both the high beam and low beam headlight positions with the same unit across the full 1950-1954 range.
The ANSI standardization of the H6006 means the unit conforms to a defined interchangeability specification, allowing replacement units from different manufacturers to fit the same housing provided they meet the H6006 designation.
