Additional Notes

The Porsche 968 uses the DE3423 bulb for the license plate position across all documented model years, spanning 1992-1995.
The DE3423 is a festoon-type bulb, meaning it is cylindrical in shape and seats between two spring-loaded end caps rather than fitting into a socket with a base pin or bayonet mount.
The bulb measures 41mm in length, which is the critical fitment specification for festoon bulbs, as housing cavities are sized to match this figure precisely.
End-cap contacts on the DE3423 mean electrical connection is made at both flat ends of the bulb, a design typical of festoon configurations used in enclosed license plate lamp housings.
The DE3423 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this type.
The DE3423 designation follows ANSI standards applicable in the United States and Canada, indicating the bulb conforms to a defined set of dimensional and performance criteria recognized across North American markets.
Because the 1992-1995 Porsche 968 shares a single bulb specification across all four model years, there are no year-specific fitment variations within this range for the license plate position.
