Additional Notes

The Kia Sedona uses two distinct courtesy bulb sizes across its model years, with the DE3175 fitted to 2002-2005 models and the DE3423 fitted to 2006-2014 models.
Both the DE3423 and DE3175 are festoon-type bulbs, meaning they are cylindrical in shape and make electrical contact through metal caps at each end rather than through a base socket.
The DE3423 has a 41mm length, while the DE3175 has a 31mm length. This 10mm difference makes the two bulbs physically non-interchangeable despite their shared festoon design and identical 12V operating voltage.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating they meet a defined set of electrical and physical tolerances for the North American market.
The end-cap contact design of festoon bulbs requires the bulb to be seated under spring tension within a holder, so correct length is a critical fitment factor for the Sedona's courtesy light housings.
The 2006 Sedona represents the transition point between the two bulb sizes, shifting from the shorter DE3175 to the longer DE3423, which reflects a change in the courtesy light housing specification between those generations.
