Additional Notes

The Hyundai Accent trunk uses three distinct bulb types across its model years: the DE3423, the DE3022, and the 12961. These are not interchangeable, as each has a different physical form and contact type.
The DE3022 and DE3423 are both ANSI-standardized festoon bulbs rated at 12V with end-cap contacts, but they differ in length. The DE3022 measures 31mm, while the DE3423 measures 41mm. Installing one in place of the other will result in a poor or failed fitment due to the length difference.
The DE3022 is the trunk bulb for the Hyundai Accent across 1995-1999 and 2003-2005. Its 31mm festoon format was the standard for this application across those years.
The 12961 is a Philips part number for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. Its wedge base design is physically incompatible with the festoon sockets used by the DE3022 and DE3423.
The 2019-2020 Accent trunk uses the 12961 wedge bulb, which represents a different socket type from the festoon-based bulbs used in other model years. A festoon bulb cannot be substituted in a wedge socket.
The 2021-2022 Accent trunk uses the DE3423, a 41mm festoon bulb. While it shares the same end-cap contact style as the DE3022, the longer body of the DE3423 means it requires a socket designed to accommodate the 41mm span.
