Additional Notes

The Nissan 350Z uses the DE3175 bulb for the map light across the 2003-2005 model years.
The DE3175 is an ANSI-standardized bulb designation, meaning it conforms to a defined specification recognized across the United States and Canada.
The DE3175 is a festoon-type bulb, which is a cylindrical form factor held in place by spring-loaded contacts at each end rather than a socket base.
The end-cap contact design of the DE3175 means the bulb makes its electrical connection through metal caps at both ends of the tube.
The DE3175 has a nominal length of 31mm, which is a critical fitment factor, as festoon bulbs must physically span the distance between their retaining contacts.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
Because the DE3175 is an ANSI-designated part, equivalent bulbs from different manufacturers carrying the same designation are generally considered interchangeable, provided they match the 31mm length and end-cap contact type.
