Additional Notes

The DE3175 is the dome light bulb size for the Saab 9-2X across both available model years, 2005-2006.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in form 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 that differs from wedge or bayonet base designs.
The DE3175 has a nominal length of 31mm, which is the measurement between the two end contacts and determines physical fitment within the dome light housing.
The DE3175 operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards, indicating the bulb conforms to specifications recognized in the United States and Canada.
