Additional Notes

The DE3423 is a festoon-type bulb measuring 41mm in length, operating at 12V, and making contact through end-caps at both ends of the housing. It conforms to ANSI standards applicable in the US and Canada.
The DE3022 shares the same festoon construction and 12V operating voltage as the DE3423 but has a shorter 31mm length. It also uses end-cap contacts and meets the same ANSI standards.
Festoon bulbs are cylindrical lamps held in place by spring-loaded contacts that press against each end-cap. The length of the bulb is the primary factor determining whether it fits a given housing.
The Kia Rio uses the DE3423 for the trunk across the 2006-2011 and 2023 model years, while the 2001-2002 model years require the shorter DE3022.
The 10mm difference in length between the DE3423 and DE3022 means the two bulbs are not interchangeable, as a shorter bulb may fail to maintain contact in a housing designed for the longer size, and a longer bulb will not seat correctly in a shorter housing.
Both bulb types operate at 12V, which is consistent with standard 12-volt automotive electrical systems.
