Additional Notes

The Mercedes-Benz G63 AMG uses the DE3423 bulb for its license plate lighting across the 2013-2018 model years.
The DE3423 is a festoon-type bulb, which means it is cylindrical in shape and makes electrical contact through metal caps at both ends rather than through a base socket.
This bulb follows the ANSI standard, meaning it conforms to specifications recognized in both the United States and Canada.
The DE3423 has a length of 41mm, which is a defining fitment factor for festoon bulbs, as the end-cap contacts must bridge the holder at a precise span to make proper electrical contact.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Because festoon bulbs are sized by their length and contact style, substituting a festoon bulb of a different length would result in an improper fit even if the voltage rating matches.
