Additional Notes

The DE3175 is a festoon-type bulb measuring 31mm in length with end-cap contacts at each end. It operates at 12 volts and follows the ANSI standard for the US and Canadian markets. This bulb type is specified for the Hyundai Veloster N dome light across the 2019-2021 model years.
The 904 is a miniature wedge bulb of the T10 type, rated at 12 volts and 8 watts, also conforming to the ANSI standard for the US and Canadian markets. It is specified for the 2022 model year dome light.
Festoon bulbs like the DE3175 make contact through their two flat or rounded end caps, which press against spring-loaded holders inside the fixture. Wedge bulbs like the 904 instead use a pinched glass base that wedges directly into a socket without a separate cap or base.
The DE3175 and the 904 are physically and electrically distinct bulb types. The festoon format and the wedge format use incompatible socket designs, meaning the two bulbs are not interchangeable with each other.
The 2022 Hyundai Veloster N represents a change in dome light bulb type relative to the three preceding model years, shifting from the festoon DE3175 format to the T10 wedge 904 format.
The wattage of the DE3175 is not specified in the provided data, while the 904 carries an 8-watt rating. Both bulbs share the same 12-volt operating voltage.
