The Mazda Millenia tail light utilizes 7443, 1157, and 168 bulb sizes for the rear lighting components. Data for the specified vehicle covers the period from 1995 through 2002.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda Millenia inner tail light uses three distinct bulb types across its production years: the 1157, 7443, and 168.
The 1157 is the most frequently specified bulb in the Mazda Millenia inner tail light position, covering the 1995, 1997-2000 model years.
The 1157 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21W high filament and 5W low filament, conforming to ANSI standards for the US and Canadian markets.
The 7443 replaces the 1157 for the 2001-2002 model years in the inner tail light position.
Although the 7443 shares the same 12V, 21W/5W dual-filament output as the 1157, it uses a T20 wedge base rather than a bayonet base, making the two types physically non-interchangeable despite their identical wattage ratings.
The 1996 Millenia inner tail light uses the 168, a single-filament miniature wedge bulb in a T10 form factor, rated at 12V and 4.9W.
The 168 operates on a single filament, which distinguishes it functionally from the dual-filament 1157 and 7443 used in all other listed model years.
All three bulb types conform to ANSI standards applicable to the US and Canadian markets.
