Additional Notes

The DE3423 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket or pins.
The DE3423 has a rated length of 41mm, which is the span between its two end contacts and determines physical fitment within the festoon holder.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3423 designation follows ANSI standards, meaning it is a recognized specification across the United States and Canada rather than a proprietary or regional part number.
The Hyundai Tiburon uses the DE3423 for its trunk across the 1997-2001 and 2007-2008 model years, with no variation in bulb size across any of those years.
Because festoon bulbs are sized by their contact-to-contact length, substituting a festoon bulb of a different length, such as a 36mm or 44mm unit, would result in an improper fit even if the voltage rating matches.
