Additional Notes

The DE3423 and DE3022 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 distinction between the two bulb types found in these specifications is physical length. The DE3423 measures 41mm, while the DE3022 measures 31mm. This 10mm difference makes the two bulbs non-interchangeable despite their shared contact style and voltage rating.
Both bulb types operate at 12 volts and conform to ANSI standards applicable in the United States and Canada.
The DE3423 is the more widely used of the two across the Hyundai Elantra trunk bulb specifications, appearing across model years 2007-2008 and 2013-2023.
The DE3022 applies to the Hyundai Elantra for model years 1993-1995 and 1999-2003.
Because festoon bulbs are held in place by spring-loaded clips that grip the end caps, the physical length of the bulb must match the socket housing. Installing a 31mm bulb in a 41mm housing, or vice versa, would result in a poor or failed connection.
