Additional Notes

The Kia Soul uses two festoon bulb types across its model years for the luggage compartment: the DE3425 for 2020-2024 and the DE3423 for 2010-2018.
Both the DE3425 and DE3423 are ANSI-standardized bulbs, meaning they conform to a defined set of dimensional and electrical specifications recognized across the United States and Canada.
A festoon bulb is a cylindrical lamp that seats horizontally within a spring-clip or end-cap housing, making contact at both ends of the bulb rather than through a base pin or wedge.
Both bulb types share a 41mm length and operate at 12 volts, which reflects the standard low-voltage electrical system found in conventional passenger vehicles.
Despite their shared length and voltage rating, the DE3425 and DE3423 are distinct part numbers and are not listed as interchangeable within these specifications.
The end-cap contact design common to both types relies on metal caps at each end of the bulb body to complete the circuit, a construction typical of festoon lamps used in interior lighting applications.
