Additional Notes

The DE3175 is the map light bulb size for the Mitsubishi Mirage G4 across all listed model years, spanning 2017-2018 and 2021-2024.
The DE3175 follows the ANSI standard, which is the recognized specification framework used in the United States and Canada for automotive lighting components.
DE3175 is a festoon-type bulb, a form factor defined by a cylindrical body with metal end-cap contacts at both ends rather than a base socket or wedge fitting.
The "31" in the DE3175 designation refers to the bulb's 31mm length, which is the critical physical specification governing fitment within the map light housing.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Because the DE3175 uses end-cap contacts, it is not interchangeable with wedge-base bulb types, even where voltage and light output may otherwise be similar.
