Additional Notes

The DE3175 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
The DE3175 follows the ANSI standard, which is the specification system used for automotive bulbs in the United States and Canada.
The bulb measures 31mm in length, which is the figure that determines physical fitment within the dome light housing.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
The Nissan 260Z uses the DE3175 bulb for the dome light across its 1974-1975 model years.
