Additional Notes

The DE3425 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket. It measures 41mm in length and operates at 12 volts.
The DE3425 follows the ANSI standard, which is the designation system used in the United States and Canada. This classification distinguishes it from ECE-coded bulbs used in European markets.
The Hyundai Santa Fe Sport uses the DE3425 for courtesy lighting across the 2017-2018 model years, indicating a consistent fitment across both production years covered in the specifications.
Festoon bulbs of the 41mm length category are a common size in automotive interior applications, but substituting a festoon bulb of a different length risks poor contact or fitment failure, as the end-cap spacing is fixed by the housing.
