Additional Notes

The DE3175 is the dome light bulb size for the Nissan Altra EV across the 1999-2001 model years.
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 operates at 12 volts, which is standard for automotive interior lighting systems.
The 31mm length of the DE3175 is a critical fitment factor, as festoon bulbs must physically span the contact points of the fixture housing to maintain a circuit.
The DE3175 designation follows ANSI standards recognized in both the United States and Canada, indicating a standardized specification rather than a proprietary one.
