Additional Notes

The DE3175 is the sole trunk bulb type listed across all Kia Sorento model years in these specifications, spanning 2003-2024.
The DE3175 is a festoon-style 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 operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards applicable to the United States and Canada, and its 31mm length is a defining physical characteristic of this festoon type.
The 2009 Kia Sorento carries a production date qualifier, with the DE3175 specification applying only to vehicles built through December 15, 2008, indicating a mid-cycle change occurred within that model year.
Festoon bulbs of differing lengths are generally not interchangeable, as the end-cap contacts must span the fixed distance of the bulb holder precisely; substituting a bulb of a different length risks poor contact or fitment failure.
