Additional Notes

The DE3423 is an ANSI-standard festoon bulb rated at 12V, with a 41mm length and end-cap contacts, meaning electrical contact is made at both ends of the bulb rather than through a wedge base.
The bulb designated 74 is an ANSI-standard T5 miniature wedge type, rated at 12V and 1.4W, where the base itself forms the electrical connection by wedging directly into the socket.
These two bulb types use fundamentally different mounting and contact systems, making them physically incompatible with each other's sockets.
The Kia Optima glove box uses the DE3423 festoon bulb across the 2011, 2012, 2013, 2017, and 2018 model years.
The T5 wedge bulb sized 74 is specified for the 2002-2006 model years.
The 2001 Kia Optima specifies the DE3423 bulb with a production date qualifier of "From 10/1/2000," indicating this fitment applies only to vehicles built on or after that date.
The 2006 model year carries a corresponding qualifier of "To 9/30/2005," indicating the 74 bulb applies to vehicles produced up to that date, which reflects a mid-cycle production change.
The production date qualifiers on the 2001 and 2006 entries signal that two different bulb types were used within those model years, and the correct fitment depends on the vehicle's specific build date rather than the model year alone.
