Additional Notes

The Mazda B2500 map light uses two distinct bulb sizes across its model years: the 904 for 2000-2001 and the 906 for 1998-1999.
Both the 904 and 906 are ANSI-standardized bulb types recognized in the US and Canada.
Each bulb type follows the T10 miniature wedge form factor, which refers to a small, wedge-shaped base designed to friction-fit into a matching socket without a separate locking mechanism.
Both bulbs operate at 12 volts and draw 8 watts, meaning they are electrically identical in terms of power consumption and voltage requirements.
Despite sharing the same voltage, wattage, and T10 wedge base, the 904 and 906 carry different ANSI designations and are specified separately by model year, indicating they are not treated as interchangeable in these fitment listings.
