Kia Forte Glove Box Bulb Size

Additional Notes

• The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12 volts and 5 watts. The T10 designation refers to the bulb's tubular shape, and the W2.1x9.5d base is a single-contact wedge fitting commonly used in low-current interior lighting applications.
• The DE3423 is an ANSI-standard festoon bulb recognized across the United States and Canada. Festoon bulbs make contact at both ends via metal end caps rather than a wedge or pin base, and the 41mm length is a defining fitment specification for this type.
• The 12961 and DE3423 are not interchangeable. The wedge base of the 12961 and the end-cap contact design of the DE3423 require different socket types, meaning a direct substitution between the two would not be physically compatible.
• The Kia Forte uses the 12961 bulb for the glove box across the 2017-2024 model years, with the exception of 2019, 2020, and 2022, which are not represented in the specifications.
• The DE3423 festoon bulb applies to the 2014-2016 model years of the Forte for the glove box position.
• The 2013 model year specifies the 12961 bulb with a production cutoff of March 31, 2013, and the 2012 model year specifies the same bulb from a start date of May 2, 2012, indicating that mid-production changes occurred within those model years.
