Additional Notes

The DE3175 is the map light bulb size for the Mitsubishi Eclipse Cross across the 2018-2024 model years covered in these specifications.
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 or pins.
Festoon bulbs are held in place by spring-loaded clips within the housing, with the end caps pressing against the contacts at both ends of the socket.
The DE3175 has a nominal length of 31mm, which is the critical fitment factor for festoon bulbs, as a bulb of a different length will not seat correctly in the spring-clip housing.
The DE3175 operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards applicable in the United States and Canada, indicating a standardized specification for voltage, size, and contact type.
Because festoon bulbs are available in multiple lengths such as 28mm, 31mm, 36mm, and 42mm, substituting a bulb of a different length risks poor contact or failure to fit within the housing of the Eclipse Cross map light.
