Additional Notes

The DE3425 and DE3175 are both festoon-type bulbs, meaning they are cylindrical in shape and make electrical contact through metal caps at each end rather than through a base or pin configuration.
The primary difference between the two bulb types is physical length. The DE3425 measures 41mm, while the DE3175 measures 31mm. These two sizes are not interchangeable, as dome light housings are designed to hold a specific festoon length.
Both bulb types operate at 12 volts, which is standard for automotive interior lighting in 12V electrical systems.
Both the DE3425 and DE3175 conform to ANSI standards applicable in the United States and Canada, indicating a standardized specification for electrical and physical characteristics.
The Hyundai Santa Fe Sport used the DE3175 for the 2013-2016 model years, making it the longer-running fitment across the six-year span covered by these specifications.
The 2017-2018 model years require the DE3425, which is 10mm longer than the DE3175 used in prior years. Installing a 31mm bulb in a housing designed for 41mm would result in poor or no contact with the end-cap terminals.
