The DE3175 is the trunk bulb size for the Kia Niro EV across the 2023-2024 model years.
The DE3175 follows the ANSI standard, which governs bulb specifications in the United States and Canada.
As a festoon-type bulb, the DE3175 mounts horizontally between two spring-clip contacts, with the electrical connections made at each end cap rather than through a base socket.
The DE3175 has a 31mm length, which is the measurement that defines its fitment within the festoon socket housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
