Additional Notes

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. It operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 follows the ANSI standard, which is the governing specification used in the United States and Canada. Its 31mm length is a defining physical characteristic that determines whether it seats correctly within a festoon lamp holder.
The Hyundai Santa Fe Sport uses the DE3175 bulb for the trunk across the 2017-2018 model years. The 31mm festoon format is a direct fitment requirement, and substituting a festoon bulb of a different length risks poor contact or failure to seat within the housing.
