Kia Soul Luggage Compartment Bulb Size

Additional Notes

• The DE3423 and DE3425 are both ANSI-standardized festoon bulbs rated at 12V, sharing a 41mm length and end-cap contact design. The end-cap contact style means electrical contact is made at each end of the bulb rather than through side pins or a base socket.
• Festoon bulbs of this type are cylindrical in form and seat horizontally within a spring-clip or socket housing, which is the typical mounting arrangement for luggage compartment lighting in enclosed spaces.
• The Kia Soul uses the DE3423 across the 2010-2011 and 2014-2018 model years for its luggage compartment, while the 2022-2023 model years specify the DE3425 instead.
• Despite sharing the same 41mm length, 12V rating, and end-cap contact configuration, the DE3423 and DE3425 carry distinct ANSI designations, which indicates a difference in wattage or filament specification between the two types.
• Because the two bulb types differ in their ANSI designation, substituting a DE3423 for a DE3425 or vice versa is not confirmed as interchangeable by these specifications, even though their physical form is identical.
• The ANSI standardization of both bulbs under US and Canadian norms means equivalent products from different manufacturers sharing the same designation are generally considered direct replacements for one another within the same bulb type.
