The Mazda Millenia high beam headlight uses a 9005 bulb size while the low beam headlight requires a 9006 bulb size. The replacement chart covers vehicle production spanning 1995 to 2002.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda Millenia uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across all model years from 1995-2002.
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, while the 9006 operates at 12 volts and 55 watts, meaning the high beam draws more power than the low beam.
The 9005 uses a P20d base and the 9006 uses a P22d base. These two base types are physically distinct, which prevents the bulbs from being interchanged between the high and low beam sockets.
Because the 9005 and 9006 share the same voltage rating but differ in wattage and base type, substituting one for the other is not a compatible swap in the Mazda Millenia's headlight housings.
