Additional Notes

The Kia Soul EV uses the DE3175 bulb size for the map light across the 2015-2018 model years.
The DE3175 is classified as a festoon bulb, a type characterized by a cylindrical body with flat metal contacts at each end rather than a screw or bayonet base.
Festoon bulbs seat by pressing lengthwise between two spring clips within the fixture, which means the physical length of the bulb is a critical fitment factor.
The DE3175 has a 31mm length, which defines the correct span between the two end-cap contacts required for a proper fit in the map light housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows the ANSI standard used in the United States and Canada, meaning the specification applies to the North American market versions of the Kia Soul EV.
Because festoon bulbs of similar length can carry different designations depending on contact style or wattage, substituting a bulb based on length alone without confirming the DE3175 designation risks an incompatible fitment.
