Additional Notes

The DE3423 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base or pin configuration.
The DE3423 has a specified length of 41mm, which determines physical fitment within the license plate lamp housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3423 designation follows ANSI standards applicable in the United States and Canada.
The Mercedes-Benz ML450 uses the DE3423 bulb for the license plate position across the 2010-2011 model years.
