Additional Notes

The Kia Sportage courtesy bulb specifications cover model years 1995 through 2008, with three distinct bulb types used across that span: the 12961, DE3175, and DE3425.
The 12961 is a Philips part number for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. Its wedge-style base means it is held in place by friction rather than a bayonet or screw mechanism.
The DE3175 and DE3425 are both ANSI-standard festoon bulbs conforming to US and Canadian specifications. Festoon bulbs make electrical contact through metal end caps at each end rather than through a base socket.
The DE3175 has a 31mm length, while the DE3425 has a 41mm length. These two festoon bulbs are not interchangeable due to the difference in physical length, even though both operate at 12V and share the same end-cap contact design.
The Kia Sportage (1995-1996-1997) uses the DE3425, the longer of the two festoon types at 41mm.
Model years 1998-2002 use the DE3175, the 31mm festoon bulb, representing a change from the DE3425 used in earlier years.
The 12961 wedge bulb applies to model years 2005-2007 and to the 2008 model year produced up to October 1, 2007, indicating a mid-production-year specification change for the 2008 Sportage.
The 2005 model year specification for the 12961 bulb carries a start date of October 25, 2004, reflecting that the 2005 model year production began on that date rather than at the start of the calendar year.
The transition from the festoon-type DE3175 to the wedge-type 12961 represents a change in both bulb format and socket type, meaning the two are not physically interchangeable.
No single bulb type spans the full range of model years covered by these specifications, as the courtesy lamp fitment changed at least twice across the 1995-2008 production period.
