Additional Notes

The Hyundai XG350 uses two distinct bulb types for the map light across its production run: the DE3423 for 2004-2005 and the 168 for 2002-2003.
The DE3423 is a festoon-style bulb measuring 41mm in length with end-cap contacts at each end. This contact style means the bulb bridges two metal terminals within the housing rather than inserting into a socket.
The 168 is a T10 miniature wedge bulb, meaning it uses a wedge-shaped base that friction-fits directly into a socket without requiring a separate locking mechanism.
Both bulb types operate at 12 volts and conform to ANSI standards applicable in the United States and Canada.
The 168 bulb carries a rated output of 4.9 watts. The DE3423 and the 168 are not interchangeable, as they differ in both physical form and contact type.
The change in bulb type between the 2003 and 2004 model years indicates a difference in map light housing design, meaning parts from one generation are not compatible with the other.
