The Mazda MX-3 headlight bulb uses a 9004 size for both high beam and low beam applications. The replacement chart covers 1992 to 1995 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9004 bulb is the sole headlight bulb type specified for the Mazda MX-3 across all listed model years.
The 9004 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating at 12 volts with a dual-filament design rated at 65 watts on the high beam filament and 45 watts on the low beam filament.
The dual-filament construction of the 9004 means a single bulb serves both the high beam and low beam functions, which is reflected in the MX-3 specifications showing identical bulb sizes for both sub-parts across all listed years.
The 9004 uses a P29t base, a connector type specific to this bulb family and not shared with other common halogen formats such as the 9005 or 9006, which use separate single-filament designs.
The 9004 specification applies uniformly to the Mazda MX-3 for model years 1992-1995, covering every listed year for both headlight positions without variation.
Because the 9004 base and wiring configuration are unique to its bulb family, substitution with physically similar-looking halogen bulbs of a different type would not constitute a compatible replacement without confirming base and voltage compatibility.
