The Mazda 2 headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers vehicle production years spanning 2011 to 2014.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole headlight bulb type specified for the Mazda 2 across the 2011-2014 model years, covering both the high beam and low beam positions.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Because both filaments are housed in one unit, the 9003 serves both lighting functions simultaneously, which is why the same bulb size appears in both the high beam and low beam positions for the Mazda 2 (2011-2014).
The 9003 operates on a 12V electrical system, consistent with standard automotive voltage.
The bulb uses a P43t base, which is a bayonet-style mount with a 43mm flange width, and this base type determines physical fitment into the headlight housing.
The 9003 is classified under the ANSI standard, applicable in the United States and Canada, and is equivalent to the European H4 bulb in filament and voltage specifications, though the two types differ in base design and are not directly interchangeable without an adapter.
