Additional Notes

The DE3423 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.
The DE3423 measures 41mm in length, which is the span between its two end-cap contacts and determines physical fitment within the sun visor lamp housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3423 designation follows ANSI standards applicable in both the United States and Canada.
The Kia Forte uses the DE3423 for its sun visor bulb across the 2017-2018 and 2023 model years listed in the specifications.
Festoon bulbs of differing lengths are generally not interchangeable even when voltage ratings match, as an incorrect length will prevent proper contact with the housing terminals.
