Ford Five Hundred high beam headlight bulbs utilize 9005 size while low beam headlight bulbs utilize 9006 size. The replacement chart covers 2005 to 2007 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Five Hundred uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across its 2005-2007 model years.
Both the 9005 and 9006 are ANSI-standardized halogen bulb types recognized in the United States and Canada, each containing a single filament.
The 9005 operates at 12 volts and 65 watts, making it the higher-wattage of the two bulb types used in this application.
The 9006 operates at 12 volts and 55 watts, reflecting the lower power draw typical of low beam circuits compared to high beam circuits.
The 9005 uses a P20d base, while the 9006 uses a P22d base. These two base types are physically distinct and not interchangeable between sockets.
Although the 9005 and 9006 share the same operating voltage and a similar physical profile, the difference in wattage and base type means one cannot be substituted for the other in the Ford Five Hundred's headlight housings.
