The Mazda B4000 high beam and low beam headlight bulbs both utilize a 9007 bulb size. 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 B4000 uses the 9007 bulb size for both high beam and low beam headlights across all model years from 1994-2009.
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.
The 9007 uses a PX29t base, which is a specific connector type. Bulbs with a different base type are not physically compatible with this socket, regardless of other similarities in voltage or wattage.
The 9007 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
Because the 9007 handles both beam functions, the Mazda B4000 (1994-2009) does not use separate bulb types for high and low beam operation.
The 9007 is sometimes confused with the 9004 bulb, which shares a dual-filament halogen design but has a different wattage rating and an incompatible connector, making the two types non-interchangeable.
