Additional Notes

The Nissan Xterra dome light uses the DE3175 bulb across all model years from 2000-2015.
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.
Festoon bulbs are held in place by spring-loaded clips that press against the end caps, a mounting method common in interior dome and map light applications.
The DE3175 has a 31mm length, which is the standard measurement used to distinguish it from other festoon sizes such as the 28mm DE3021 or the 36mm DE3423, making size precision critical for a proper fit.
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 one.
Because the DE3175 is an ANSI-standardized festoon bulb, it is produced by multiple manufacturers, and direct-fit replacements are widely available under that designation.
The 31mm festoon format is also compatible with LED retrofit bulbs of the same length and end-cap configuration, provided the replacement unit is rated for 12V and matches the 31mm festoon form factor.
