Additional Notes

The DE3175 is the trunk bulb size for the Kia Niro across the 2018, 2023, and 2024 model years.
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 or pins.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards applicable in the United States and Canada, and the 31mm figure refers to the length of the bulb between its end caps.
The 2018 Kia Niro trunk bulb fitment applies to vehicles produced from December 9, 2016 onward, indicating a mid-cycle production date that defines the scope of that model year entry.
