Additional Notes

The DE3022 is the sole courtesy bulb size listed for the Hyundai Elantra across the 1999-2003 model years.
The DE3022 is classified as a festoon bulb, a cylindrical lamp type that seats between two spring-loaded end-cap contacts rather than using a traditional socket base.
The DE3022 operates at 12 volts, which is standard for automotive interior lighting systems powered by a lead-acid battery.
The bulb has a 31mm length, a figure that determines physical fitment within the festoon housing and is not interchangeable with festoon bulbs of differing lengths such as the 28mm or 36mm variants.
The DE3022 designation follows ANSI standards applicable in the United States and Canada, meaning the specification reflects North American market fitment for the Elantra during this period.
