Additional Notes

The Ferrari F355 GTS uses the DE3022 bulb for its dome light across the full 1994-1998 production run of the model.
The DE3022 is classified as a festoon-type bulb, meaning it is cylindrical in shape with metal end-cap contacts at each end rather than a base socket.
Festoon bulbs make contact through pressure against both end caps, which requires the mounting holder to match the bulb's length for a secure electrical connection.
The DE3022 has a specified length of 31mm, which is the critical fitment factor when considering substitute or replacement bulbs.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
The DE3022 designation follows ANSI standards, meaning it conforms to specifications recognized across the United States and Canada.
A festoon bulb of a different length, even if otherwise similar, would not seat correctly in the F355 GTS dome light holder, as the end-cap contact design depends on a precise fit between the bulb and the fixture span.
