Additional Notes

The DE3423 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base or pins.
The DE3423 follows the ANSI standard, which is the specification framework used in the United States and Canada, governing the bulb's electrical and physical characteristics.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
At 41mm in length, the DE3423 fits within a festoon holder sized to that specific span. Installing a festoon bulb of a different length risks poor contact or failure to seat correctly in the housing.
The Porsche Carrera GT uses the DE3423 bulb for the license plate position across both the 2004-2005 model years.
