Mazda 626 Headlight Bulb Size

Mazda 626 high beam and low beam headlight bulbs utilize 9003, 9005, 9004, and 9006 sizes depending on generation, with the 9003 bulb size appearing across multiple configurations. The replacement chart covers 1979 through 2002 production years and correlates each generation to its corresponding bulb specifications.

Additional Notes

The Mazda 626 headlight specifications span from 1979 to 2002, covering four distinct bulb types across that period: H6054, H4651/H4652, 9004, 9005/9006, and 9003.
The 9003 is a dual-filament halogen bulb rated at 12V with a 60W high beam filament and a 55W low beam filament, using a P43t base. Because it carries both filaments in a single unit, the Mazda 626 (1998-2002) uses the same 9003 bulb for both high and low beam positions.
The 9004 is also a dual-filament halogen bulb, rated at 12V with a 65W high beam filament and a 45W low beam filament, using a P29t base. The 626 (1986-1992) likewise uses this single bulb type for both beam functions.
For the 1993-1997 model years, the 626 uses separate single-filament bulbs for each beam function: the 9005 (65W, P20d base) handles the high beam, while the 9006 (55W, P22d base) handles the low beam. These two bulbs are not interchangeable with each other despite their similar appearance, as their bases and wattage ratings differ.
The H6054 is a 5x7-inch rectangular sealed beam unit used on the 626 from 1979-1982. As a sealed beam, the lens, reflector, and filament form a single assembly, meaning the entire unit is replaced rather than an individual bulb.
The H4651 and H4652 are 4x6-inch rectangular sealed beam units used on the 626 from 1983-1985. The H4651 serves the high beam position and the H4652 serves the low beam position. Though both share the same physical housing format, they are distinct part numbers and are not interchangeable between beam positions.
The P43t, P29t, P20d, and P22d base designations found across the halogen bulb types in these specifications indicate physically different connector configurations, meaning bulbs from different type families cannot be substituted for one another without modification to the socket.
All bulb types listed across the full 1979-2002 specification range conform to ANSI standards applicable in the United States and Canada, and all operate on a 12V electrical system.
