Additional Notes

The Nissan Armada uses the DE3175 bulb as its dome light across all listed model years, spanning 2005-2015 and 2019.
The DE3175 is a festoon-style bulb, meaning it is cylindrical in shape with metal end-cap contacts on each end rather than a base pin or wedge fitting.
Festoon bulbs are held in place by spring-loaded clips within the dome light housing, with the end caps making direct electrical contact at both terminals.
The DE3175 has a nominal length of 31mm, which is the critical fitment factor for festoon bulbs, as the housing clip spacing must match the bulb length.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards recognized in both the United States and Canada, indicating a standardized specification rather than a proprietary part number.
The 2019 Nissan Armada specification identifies the DE3175 as the rear dome light bulb specifically, distinguishing its position within the vehicle's interior lighting layout.
Because the DE3175 is an ANSI-standardized festoon bulb, aftermarket and LED replacement bulbs labeled DE3175 or 31mm festoon are generally considered interchangeable, provided the 31mm end-cap spacing is maintained.
