Additional Notes

The DE3423 is the most frequently specified trunk bulb across the Kia Sportage's history, covering model years 1998-2008 with only a brief mid-cycle exception in 2013.
The DE3423 follows the ANSI standard for the US and Canadian markets and is a festoon-type bulb measuring 41mm in length with end-cap contacts, operating at 12V.
The DE3175 is also an ANSI-standard festoon bulb with end-cap contacts operating at 12V, but its length is 31mm, making it physically shorter than the DE3423 and not interchangeable with it despite sharing the same contact style.
The 12961 is a Philips part number designating a miniature wedge-type bulb in the T10 form factor, using a W2.1x9.5d base, rated at 12V and 5W. Its wedge base design is fundamentally different from the end-cap festoon format used by both the DE3175 and DE3423.
The Kia Sportage (2017-2019) uses the DE3175, while the 2015-2016 model years use the 12961, meaning these two consecutive generation groups require bulbs of entirely different base types.
A mid-production change occurred during the 2013 model year. Units produced before March 25, 2013 take the DE3423, while those produced from that date onward take the 12961, requiring the production date to be confirmed before selecting a replacement.
A similar production-date-specific fitment applies to the 2014 model year, where the 12961 is specified only for vehicles produced from September 27, 2013 onward.
The 2010 model year carries a production date qualifier as well, with the DE3423 specified only for vehicles produced from April 29, 2010 onward.
The 2007 model year specification notes the DE3423 applies to vehicles produced through December 31, 2006, indicating an early production window relevant to that model year's fitment.
Because the three bulb types in these specifications span two distinct base designs and three physical configurations, substituting one for another without confirming the correct size and base type would result in an incompatible fitment.
