The Mazda 929 uses high beam headlight bulbs in 9005 and 9004 sizes, while low beam headlight bulbs measure 9006 and 9004 in size. The replacement chart covers vehicle production years from 1988 to 1995 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda 929 headlight bulb specifications cover the 1988-1995 model years, with two distinct bulb configurations used across that span.
The 9004 bulb is a dual-filament halogen type rated at 12V with a 65W high beam filament and a 45W low beam filament, fitted with a P29t base. In the 1988-1991 Mazda 929, a single 9004 bulb serves both the high beam and low beam functions within one housing.
Starting with the 1992 model year, the 929 moved to a split-bulb arrangement, using a dedicated 9005 for high beam and a dedicated 9006 for low beam, replacing the dual-function 9004 entirely.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base. It handles only the high beam function in the 1992-1995 929.
The 9006 is a single-filament halogen bulb rated at 12V and 55W, fitted with a P22d base. It handles only the low beam function in the 1992-1995 929.
All three bulb types, the 9004, 9005, and 9006, conform to ANSI standards applicable in the United States and Canada.
The P20d, P22d, and P29t base designations are physically distinct from one another, meaning the 9004, 9005, and 9006 bulbs are not interchangeable despite sharing the same 12V operating voltage.
Owners of 1992-1995 929 vehicles require two separate bulb part numbers to service the headlight system, whereas the 1988-1991 929 requires only the single 9004 part number for both beams.
