Additional Notes

The Kia Forte Koup glove box uses two distinct bulb types across its model years: the DE3423 festoon bulb and the 12961 miniature wedge bulb.
The DE3423 is an ANSI-standard festoon bulb rated at 12V, measuring 41mm in length with end-cap contacts. Festoon bulbs seat by pressing lengthwise between two spring clips rather than inserting into a socket.
The 12961 is a Philips-designated miniature wedge bulb of the T10 type, fitted with a W2.1x9.5d base and rated at 12V, 5W. Wedge bulbs are held in place by friction from the base itself, with no separate locking mechanism.
The DE3423 and 12961 use fundamentally different base types, making them physically incompatible with each other's sockets. One cannot substitute for the other without a housing modification.
The Kia Forte Koup (2014-2016) uses the DE3423 festoon bulb for the glove box.
The 12961 wedge bulb was specified for the 2012 model from 05/02/2012 onward, and for the 2013 model through 3/31/2013, indicating a mid-production transition between the two bulb types.
The date-based fitment boundaries on the 2012 and 2013 model years mean that vehicles produced outside those windows may carry a different glove box bulb specification, and production date rather than model year alone determines the correct bulb for those vehicles.
