Additional Notes

The Ford Aspire uses the DE3175 bulb size for its dome light across the 1994-1997 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, consistent with the standard electrical system voltage found in passenger vehicles.
The 31mm length designation in the DE3175 specification refers to the distance between the two end-cap contacts, which determines physical fitment within the dome light housing.
The DE3175 carries an ANSI designation, indicating it conforms to a standardized specification recognized in both the United States and Canada.
Because the DE3175 is an ANSI-standardized festoon bulb, other bulbs sharing the same 31mm contact-to-contact length and end-cap configuration are generally considered interchangeable, provided voltage ratings are compatible.
