Additional Notes

The Mazda Tribute uses the 912 bulb size for its dome light across the 2001-2006 and 2008-2011 model years.
The 912 is an ANSI-standardized bulb type, meaning its specifications are governed by a formal industry standard recognized in both the United States and Canada.
The 912 bulb uses a wedge-style base, classified under the T15 designation, which refers to a tubular bulb body approximately 15/8 of an inch wide.
The 912 operates at 12 volts and 12 watts, which is consistent with standard automotive low-voltage electrical systems.
The 912 is a variant of the 921 bulb. While the two share the same T15 wedge form factor and 12-volt rating, the 921 is rated at 18 watts, making the two bulbs non-interchangeable despite their physical similarity.
Because the 912 and 921 share the same wedge base, the 921 can physically fit the Mazda Tribute dome light socket, but its higher wattage output may exceed the thermal tolerances of the socket and surrounding housing.
