Mazda MPV high and low beam headlight bulbs utilize 9003 and 9004 bulb sizes across multiple production generations. The replacement chart covers 1989 through 2006 model 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 Mazda MPV uses two distinct bulb types across its headlight specifications: the 9003 and the 9004, both of which are ANSI-standard dual-filament halogen bulbs rated at 12 volts.
The 9003 bulb carries wattage ratings of 60W for high beam and 55W for low beam, while the 9004 is rated at 65W for high beam and 45W for low beam, reflecting different power distributions between the two types.
The 9003 uses a P43t base and the 9004 uses a P29t base. These base types are physically incompatible with each other, meaning one cannot be substituted for the other without a fitment mismatch.
Because both the high beam and low beam positions on the Mazda MPV use the same bulb type for any given model year, a single bulb type serves both functions in each headlight assembly.
The 9003 bulb is specified for the Mazda MPV across the 1996-2006 model years, with no entry present for 1999, while the 9004 is specified for the 1989-1995 model years.
The transition from the 9004 to the 9003 represents a change in both base type and wattage distribution, with the 9003 drawing less power on high beam but more on low beam compared to the 9004.
Since both bulb types are dual-filament designs, a single bulb in each headlight housing handles both high and low beam output, rather than requiring separate bulbs for each function.
