Additional Notes

The DE3175 is the dome light bulb size for the Mitsubishi Cordia across the 1983-1985 model years.
The DE3175 follows the ANSI standard, making it applicable to vehicles sold in the United States and Canada.
As a festoon-type bulb, the DE3175 is cylindrical in form and seats between two spring-loaded end-cap contacts rather than fitting into a socket with a base pin or bayonet mount.
The DE3175 has a 31mm length, which is a defining fitment specification for this bulb type, as festoon bulbs of differing lengths are not interchangeable even when they share the same contact style.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage of passenger vehicles of that era.
