Additional Notes

The Nissan 710 uses the DE3175 bulb for the dome light across the 1974-1977 model years.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket.
The DE3175 operates at 12 volts, which is consistent with standard automotive electrical systems of that era.
The 31mm length in the DE3175 designation refers to the physical span between the two end caps, which must match the holder spacing in the vehicle's dome light fixture for proper fitment.
The DE3175 carries an ANSI designation, indicating it conforms to a standardized specification recognized in both the United States and Canada.
Because the DE3175 is an ANSI-standardized festoon bulb, other bulbs sharing the same 31mm length and end-cap contact design may be physically interchangeable, provided they also match the 12-volt operating requirement.
