The Mazda B2500 high beam and low beam headlight bulbs both utilize a 9007 size. The replacement chart covers vehicle production spanning 1998 to 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda B2500 uses the 9007 bulb for both high beam and low beam headlights across all listed model years, 1998-2001.
The 9007 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 65W for high beam operation and one rated at 55W for low beam operation.
Because the 9007 handles both beam functions within one unit, the B2500 does not require separate bulbs for high and low beam headlights.
The 9007 operates on a 12V electrical system, which is standard for passenger vehicle applications.
The 9007 uses a PX29t base, which is a specific connector type. Bulbs with different base configurations are not physically interchangeable with this socket, regardless of wattage similarity.
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 dimensional specifications shared across manufacturers.
The 9006 and 9005 are single-filament bulbs that share a similar appearance with the 9007 but are not interchangeable with it due to differences in base design and filament configuration.
