Additional Notes

The Mercedes-Benz E430 uses the DE3423 bulb for the license plate position across all listed model years, spanning 1998-2002.
The DE3423 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at both ends rather than through a base or pins.
The DE3423 has a length of 41mm, which is a standard festoon size widely used in European and North American vehicle applications.
The bulb operates at 12 volts, consistent with the standard electrical systems found in passenger vehicles.
The DE3423 designation follows ANSI standards, indicating it meets defined performance and physical specifications recognized in both the United States and Canada.
Because the DE3423 is an ANSI-standardized festoon bulb, aftermarket and OEM replacements from different manufacturers are generally interchangeable as long as they share the same 41mm length and end-cap contact design.
Festoon bulbs of differing lengths are not interchangeable even when they share the same contact style, as an incorrect length will prevent proper seating within the license plate lamp housing.
