Additional Notes

The Ford Contour uses the DE3423 bulb for the license plate position across all listed model years, spanning 1995-2000.
The DE3423 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at both ends rather than through a base socket or pins.
At 41mm in length, the DE3423 falls within the standard range for festoon bulbs used in license plate and interior lighting applications.
The DE3423 operates at 12 volts, which is consistent with standard automotive electrical systems.
The DE3423 carries ANSI designation, indicating it meets standardized specifications recognized in both the United States and Canada.
Because the DE3423 is an ANSI-standardized festoon bulb, aftermarket and OEM replacements from different manufacturers are generally interchangeable as long as they share the same 41mm length, end-cap contact design, and 12V rating.
Festoon bulbs of differing lengths are not interchangeable even when they share the same voltage rating, as the physical fit within the housing depends on the bulb spanning the correct distance between the two contact points.
