Additional Notes

The DE3175 is the dome light bulb size for the Kia K5 across the 2021-2024 model years.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket.
The bulb measures 31mm in length, which is the standard reference figure used to match festoon bulbs to their housing slots.
The DE3175 operates at 12 volts, consistent with the standard electrical systems found in passenger vehicles.
This bulb conforms to the ANSI standard, indicating it meets the specifications recognized in the United States and Canada for interchangeability and performance.
Festoon bulbs are not universally interchangeable across all lengths; a replacement must match the 31mm specification to seat correctly within the K5 dome light housing.
