Additional Notes

The 904 bulb is the specified courtesy bulb size for the Kia Niro across the 2021-2023 model years.
The 904 is classified as a miniature wedge bulb, using a T10 base, which is a push-in, pin-free base type that seats directly into a wedge socket without a separate holder or pins.
The bulb operates at 12 volts and draws 8 watts, consistent with low-current interior lighting applications such as courtesy lamps.
The 904 designation follows the ANSI standard, which applies to the United States and Canada, meaning the specification is validated for vehicles sold in those markets.
T10 wedge bulbs are produced by multiple manufacturers under various part numbers, and cross-compatibility depends on matching the voltage, wattage, and base type rather than the number alone.
