Additional Notes

The DE3175 is a festoon-type bulb measuring 31mm in length with end-cap contacts, operating at 12V. Festoon bulbs seat into spring-loaded clips at both ends of a dome light housing, with the metal caps at each tip serving as the electrical contacts.
The 904 is a miniature wedge bulb in the T10 form factor, rated at 12V and 8W. Wedge bulbs use a pinched glass base with embedded wire leads in place of a separate metal base, allowing them to be pressed directly into a socket without a separate locking mechanism.
Both the DE3175 and 904 conform to ANSI standards applicable in the United States and Canada, meaning their electrical and physical specifications follow a standardized definition within those markets.
The Kia Seltos uses the DE3175 for the 2024 model year and the 904 for the 2023 model year. These are distinct bulb types with different form factors, and they are not interchangeable with each other despite both operating at 12V.
The DE3175 and 904 differ in base type, physical form, and wattage rating. Installing the incorrect type risks either a poor electrical connection or physical incompatibility with the dome light housing for that model year.
