Additional Notes

The Mitsubishi Eclipse dome light uses two bulb types across its model years: the DE3175 and the 562. Both are festoon-style bulbs operating at 12 volts and conforming to ANSI standards recognized in the US and Canada.
Festoon bulbs are cylindrical lamps that make electrical contact through metal caps at each end rather than through a base socket. This end-cap contact design is a defining characteristic shared by both the DE3175 and the 562.
The DE3175 is 31mm in length, while the 562 is 44mm in length. Because the two bulbs differ in physical size, they are not interchangeable despite sharing the same festoon contact style and operating voltage.
The 562 carries a rated wattage of 12W. No wattage is specified for the DE3175 in these specifications.
The Mitsubishi Eclipse (2006-2011) uses the DE3175 for the dome light across all six of those model years.
The 2003-2005 Eclipse models require the 562 bulb for the dome light, making those three years distinct from the rest of the model range covered in these specifications.
The 1990-2002 Eclipse models all use the DE3175, representing the longest continuous stretch of a single bulb fitment in these specifications.
The 2003-2005 model years represent a period where the longer 44mm 562 bulb was fitted. Installing a 31mm DE3175 in a housing designed for the 44mm 562 would result in improper contact and lamp failure.
