Additional Notes

The Kia Forte Koup uses the DE3175 bulb for the map light across all listed model years, spanning 2010-2016.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
The 31mm figure in the DE3175 designation refers to the length of the bulb, which is the critical fitment factor for festoon bulbs installed in fixed-width holders.
The DE3175 operates on a 12-volt circuit, consistent with standard automotive electrical systems.
DE3175 is an ANSI-standardized designation, meaning the specification is recognized across the United States and Canada, and bulbs sold under this number from different manufacturers are expected to share the same physical and electrical characteristics.
Because the DE3175 is an end-cap contact festoon bulb, substitutes must match both the 31mm length and the end-cap contact style to seat correctly in the Forte Koup map light housing.
