Additional Notes

The Mitsubishi Mirage dome light uses the DE3175 bulb across all listed model years, spanning 1989-2002 and 2014-2020.
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 "31" in the DE3175 designation refers to the bulb's 31mm length, which is the critical physical specification governing fitment in the dome light housing.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The DE3175 carries an ANSI designation, indicating it conforms to a standardized specification recognized in the United States and Canada.
Because the DE3175 is an ANSI-standardized festoon bulb, it is interchangeable with other bulbs sharing the same 31mm length and end-cap contact configuration, provided the voltage rating matches.
Festoon bulbs of differing lengths, such as 28mm or 36mm variants, are not compatible with housings specified for the 31mm DE3175, as the end caps would not make proper contact.
