Additional Notes

The Kia Spectra dome light uses two distinct festoon bulb sizes across its model years: the DE3423 and the DE3175.
Both the DE3423 and DE3175 are ANSI-standardized bulbs recognized in the United States and Canada, and both operate at 12 volts.
A festoon bulb is a cylindrical lamp that makes electrical contact through metal caps at each end rather than through a base pin or wedge, which is reflected in the end-cap contact design of both bulb types.
The DE3423 measures 41mm in length, while the DE3175 measures 31mm, making the two bulbs physically incompatible with each other despite sharing the same festoon form factor and voltage rating.
The Kia Spectra (2007-2009) requires the DE3423 bulb for the dome light position.
The DE3175 bulb is specified for the Kia Spectra across the 2000-2001 and 2005-2006 model years.
Because the DE3423 and DE3175 differ in length by 10mm, substituting one for the other in a dome light housing would result in an improper fit, as festoon housings are sized to hold a specific bulb length under spring tension.
The shared end-cap contact design means both bulbs seat in the same general style of festoon holder, but the holder span must match the specific bulb length to maintain reliable electrical contact.
