Additional Notes

The DE3175 is the map light bulb size for the Scion xA across the 2004-2006 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 bulb has a 31mm length, which is the span between its two end-cap contacts and determines physical fitment within the map light housing.
The DE3175 operates at 12 volts, consistent with standard automotive electrical systems.
This bulb conforms to ANSI standards as recognized in the United States and Canada, indicating it meets a defined set of electrical and physical specifications shared across compliant manufacturers.
