The Mazda B3000 headlight assembly uses 9007 bulb size for both high beam and low beam functions. The replacement chart covers vehicle production spanning 1994 to 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda B3000 uses the 9007 bulb type across all listed model years (1994-2007) for both high beam and low beam headlight positions.
The 9007 is a dual-filament halogen bulb, meaning a single bulb 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 keyed connector configuration. Bulbs with different base types are not physically interchangeable with this socket, regardless of similar wattage or voltage ratings.
The 9007 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of performance and construction specifications under that standard.
Because the 9007 handles both beam functions, the Mazda B3000 headlight assembly does not use separate bulbs for high and low beams, distinguishing it from systems that require two distinct bulb types per headlight.
