Additional Notes

The Hyundai Elantra GT uses the DE3175 bulb size for the trunk across the 2016-2019 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 socket.
The DE3175 has a 31mm length, which is the span between its two end contacts and determines physical fitment within the trunk lamp housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards recognized in both the United States and Canada, indicating the bulb conforms to a defined set of dimensional and performance specifications.
Because the DE3175 is an ANSI-standardized festoon bulb, other festoon bulbs of differing lengths are not interchangeable, as the end contacts must span the correct distance to seat properly in the lamp holder.
