Additional Notes

The Kia Niro uses the 904 bulb for its courtesy lighting across the 2020-2024 model years.
The 904 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the US and Canada.
It belongs to the T10 miniature wedge family, a form factor defined by a wedge-shaped base that connects directly into a socket without a separate metal cap or pins.
The 904 operates at 12 volts, which is consistent with standard automotive electrical systems.
Its rated wattage is 8W, placing it in the low-power range typical of interior courtesy applications such as dome, map, and door-area lighting.
The wedge base design of the T10 means fitment depends on socket compatibility with that specific base type, and bulbs with pin-style or bayonet bases are not interchangeable with it.
