The Mazda B2300 uses a 9007 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1994 to 2009.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda B2300 uses the 9007 bulb size for both high beam and low beam headlights across all specified model years from 1994-2001 and 2003-2009.
The 9007 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions within one housing.
The 9007 operates on a 12-volt electrical system and draws 65 watts on the high beam filament and 55 watts on the low beam filament, reflecting the differing brightness demands of each mode.
The 9007 uses a PX29t base, which is a specific keyed connector configuration. Bulbs with a different base type are not physically interchangeable with this fitment even if their wattage ratings are similar.
The 9007 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to defined performance and construction standards within those markets.
Because the same 9007 bulb serves both beam functions in the Mazda B2300, replacing only the high beam or only the low beam is not possible independently; the entire bulb unit is replaced in either case.
