Additional Notes

The Mercedes-Benz ML55 AMG uses the DE3423 bulb for the license plate position across the 2000-2003 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 or pins.
The DE3423 has a 41mm length, which is the span between its two end caps and determines physical fitment within the license plate lamp housing.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this type.
The DE3423 carries an ANSI designation, meaning it conforms to a standardized specification recognized in both the United States and Canada, which governs its electrical and physical characteristics.
Because festoon bulbs are sized by length, any replacement must match the 41mm specification to seat correctly within the lamp housing contacts.
