Additional Notes

The Mitsubishi Outlander Sport uses the DE3175 bulb size for the map light across all listed model years, spanning 2011-2020.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at both ends rather than through a base socket.
The DE3175 has a 31mm length, which is the measurement between its two end caps and determines physical fitment within the map light housing.
This bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards, indicating it conforms to specifications recognized across the United States and Canada.
Because the DE3175 is an ANSI-standardized festoon bulb, aftermarket and OEM replacements from different manufacturers sharing this designation are generally interchangeable, provided the 31mm length and end-cap contact design are maintained.
Festoon bulbs of similar length designations, such as the DE3021 or DE3022, differ in length or contact style and are not direct substitutes for the DE3175 in this application.
