Additional Notes

The BMW X6 uses the DE3423 bulb for the license plate position across the 2008-2014 model years.
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.
Festoon bulbs are held in place by spring-loaded clips within the housing, with the end caps pressing against the contacts to complete the circuit.
The DE3423 has a nominal length of 41mm, which is a critical fitment factor, as festoon bulbs must match the span between the housing contacts to seat correctly.
The bulb operates on a 12-volt circuit, consistent with the standard electrical system voltage found in passenger vehicles.
The DE3423 designation follows the ANSI standardization system used in the United States and Canada, which defines the bulb's physical and electrical characteristics.
Because the DE3423 is an ANSI-standardized type, it is interchangeable with any other bulb carrying the same designation, regardless of manufacturer, provided the 41mm length and end-cap contact design are maintained.
Festoon bulbs of differing lengths, such as 36mm or 44mm types, are not compatible with this application even if they share a similar appearance, as the contact span would not align correctly.
