Additional Notes

The DE3175 is the dome light bulb used across all documented model years of the Kia Cadenza, spanning 2017-2019.
The DE3175 follows the ANSI standard, which is the bulb classification system used in the United States and Canada.
As a festoon-type bulb, the DE3175 is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
The 31mm length of the DE3175 refers to the distance between its two end-cap contacts, which is the critical fitment factor for festoon bulbs in dome light housings.
The DE3175 operates at 12 volts, consistent with standard automotive electrical systems.
The consistent use of the DE3175 across the 2017-2019 Kia Cadenza indicates that the dome light housing specification did not change across those model years, making the bulbs interchangeable between them.
