Mazda MPV Map Light Bulb Size

The Mazda MPV map light utilizes bulb sizes 12961, 168, and 194 depending on the specific version of the vehicle. Data for the bulb sizes covers the range from 1993 to 2006.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Mazda MPV map light specifications reference three bulb sizes across the 1993-2006 model years: 12961, 168, and 194. All three are T10 miniature wedge bulbs, meaning they share the same physical wedge-style form factor despite carrying different part designations.
The 168 bulb is the most frequently specified of the three. It is designated under the ANSI standard used in the US and Canada, operates at 12V, and draws 4.9W. It is specified for the Mazda MPV across the 1993, 1995-2003 model years.
The 12961 is a Philips-branded part number rather than an ANSI designation. It is a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It is specified for the 2004-2006 model years.
The W2.1x9.5d base notation on the 12961 bulb describes a standardized wedge base where 2.1 refers to the wire contact width in millimeters and 9.5 refers to the insertion depth in millimeters. This is the IEC/ISO designation for the base type that corresponds to the T10 wedge form.
The 168 and 12961 bulbs both use the T10 wedge form factor and operate at 12V, with a wattage difference of only 0.1W between them. This close electrical similarity reflects their shared base type and general interchangeability within T10 wedge sockets.
The 194 bulb is specified solely for the 1994 Mazda MPV map light. Like the 168, it carries an ANSI designation and operates at 12V, but it draws 3.78W, which is notably lower than the 4.9W rating of the 168.
Although the 168 and 194 are both ANSI-standard T10 wedge bulbs with the same base type, their wattage ratings differ. Substituting one for the other in a socket designed for a specific wattage may affect brightness output, as the 194 produces less light than the 168 under the same 12V supply.
The 12961 designation reflects Philips' internal part numbering system rather than a universal industry standard. The underlying bulb specification it represents is functionally equivalent to the T10 wedge category, which is why it shares physical compatibility with ANSI-coded bulbs of the same base type.
