Additional Notes

The DE3175 is the dome light bulb size for the Kia Niro EV across the 2023-2024 model years.
The DE3175 follows the ANSI standard, making it the applicable specification for the United States and Canada markets.
As a festoon-type bulb, the DE3175 sits horizontally between two end-cap contacts rather than fitting into a socket base, which is a common configuration in automotive interior lighting.
The DE3175 has a 31mm length, which is the defining physical attribute that determines fitment within the dome light housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
