Additional Notes

The Kia Forte5 glove box uses two distinct bulb types across its model years: the 12961, a miniature wedge bulb, and the DE3423, a festoon-style bulb.
The 12961 is a Philips part number designating a T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The T10 designation refers to a tubular bulb approximately 10/32 of an inch wide, and the W2.1x9.5d base is a wedge-type fitting that requires no socket pins, relying instead on wire contacts gripping the base directly.
The DE3423 follows the ANSI standard used in the United States and Canada, classifying it as a festoon bulb with a 41mm length and end-cap contacts, rated at 12V.
Festoon bulbs make electrical contact through metal caps at each end of the bulb body, which seat into spring-loaded holders rather than a keyed socket.
The Kia Forte5 (2017-2018) uses the 12961 wedge bulb for the glove box, while the 2014-2016 model years use the DE3423 festoon bulb.
The two bulb types are not interchangeable, as the wedge and festoon formats use fundamentally different socket designs and contact mechanisms.
The DE3423 does not carry a wattage specification in the provided data, whereas the 12961 is explicitly rated at 5W.
