Additional Notes

The DE3423 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at both ends rather than through a base socket.
The DE3423 follows the ANSI standard, which is the recognized specification framework for automotive lighting components in the United States and Canada.
At 41mm in length, the DE3423 belongs to the mid-range festoon category, and correct length is critical for fitment since festoon holders are sized to match specific bulb lengths.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The Mercedes-Benz G65 AMG uses the DE3423 for its license plate bulb across the 2016-2018 model years.
Because festoon bulbs rely on end-cap tension for contact, substituting a bulb of a different length risks poor electrical contact or failure to seat within the housing.
