Additional Notes

The 904 is a T10 miniature wedge bulb rated at 12V and 8W, designed with a wedge-shaped base that clips directly into a socket without requiring a separate holder or pins.
The DE3175 is a 31mm festoon bulb that makes contact through metal end caps on each end of the tube, a form factor commonly used in interior dome and map light applications.
Both the 904 and DE3175 conform to ANSI standards applicable in the US and Canada, meaning they meet defined electrical and physical tolerances for those markets.
The 2023 Hyundai Kona N uses the 904 bulb for the dome light, while the 2022 model uses the DE3175, indicating that these two bulb types are not interchangeable between model years despite serving the same function.
The wedge base of the 904 and the end-cap contact design of the DE3175 represent physically distinct mounting systems, which means a socket built for one will not accept the other without modification.
The DE3175 specification does not include a wattage rating, whereas the 904 is rated at 8W, so power draw characteristics differ between the two model years.
