Additional Notes

The DE3423 is the license plate bulb size for the Mercedes-Benz B Electric Drive across the 2014-2015 model years.
The DE3423 follows the ANSI standard, which governs bulb specifications for the United States and Canadian markets.
As a festoon-type bulb, the DE3423 is cylindrical in form and seats between two end-cap contacts rather than using a base socket, which is a common fitment method for enclosed license plate lamp housings.
The DE3423 has a length of 41mm, a measurement that determines physical fit within the lamp cavity and is not interchangeable with festoon bulbs of differing lengths.
The DE3423 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
