Additional Notes

The Land Rover Discovery uses the DE3423 bulb for the license plate position across the 1994-2004 model years.
The DE3423 is a festoon-type bulb, which means it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket or pins.
The bulb measures 41mm in length, which is the span between its two end-cap contacts and determines physical fitment within the license plate housing.
The DE3423 operates on a 12-volt electrical system, consistent with the standard automotive voltage found in the Land Rover Discovery.
The DE3423 designation follows ANSI standards, meaning it is a specification recognized across the United States and Canada rather than a proprietary or region-specific part number.
Festoon bulbs of the same length are not always interchangeable, as contact cap design and voltage rating can differ between part numbers even when the physical length appears similar.
