The Mazda MPV tail light utilizes bulb size 7443 and bulb size 1157 for the rear lighting components. Data for the specified vehicle covers the range from 1996 through 2006.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1157 bulb is one of the two most frequently specified sizes across the Mazda MPV tail light data. It is an ANSI-standard dual-filament bulb with a BAY15d bayonet base, rated at 12V and 21W/5W, where the higher wattage filament serves braking or turn functions and the lower wattage filament serves running light functions.
The 7443 bulb shares the same 12V, 21W/5W dual-filament rating as the 1157 but uses a T20 wedge form factor rather than a bayonet base. These two bulbs are not interchangeable despite identical wattage ratings, as their base types are physically incompatible.
The Mazda MPV outer tail light position transitioned from the 1157 bayonet-base bulb to the 7443 wedge-base bulb between the 1998 and 2000 model years, reflecting a base-type change at that position.
The 7443 bulb is specified for both the outer tail light and the upper tail light on the 2002-2006 Mazda MPV, meaning both positions share the same bulb size during that generation.
The 168 bulb is a miniature T10 wedge type rated at 12V and 4.9W. It is a single-filament, low-wattage bulb suited to indicator or courtesy light roles rather than primary stop or turn functions.
The 12961 is a Philips part number designation for a miniature T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. Its wattage is nearly identical to the 168 bulb, though the two carry different designation systems and are not confirmed interchangeable by the specifications.
The inner tail light position on the 1989-1995 Mazda MPV uses the 168 bulb exclusively, while the outer tail light on the same model years uses the 1157. The two positions therefore require different bulb types despite being part of the same tail light assembly generation.
The lower tail light position, present only in the 2002-2006 generation data, uses the 12961 bulb, which is a single-filament T10 type. This contrasts with the outer and upper positions on the same vehicles, which use the dual-filament 7443.
