This is a little KUAL extension that leverages the method on this thread to allow a sort of fake night mode on non-PW Kindles (i.e. ones where night mode is not supported).
As it uses fbdepth and fbink, it requires USBNet installed.
Caveats:
To install, just drop the contents of the zip file inside the extensions folder on the internal storage.

Caveats:
- I've tested this only on my KT4, I'm not really sure how it'll behave on other models - worse case scenario, if it breaks horribly, like the screen blanks out, freezes, or doesn't seem to respond to touches, you may need to force reboot your Kindle;
- When in night mode, ghosting effects are much more pronounced; you'll either have to force a screen refresh very often (by touching the status bar, then back at the center of the book) or just leave page refresh on all time time (Settings > Reading Options > Page Refresh). YMMV, of course, that was just my experience with the KT4;
- The night mode setting doesn't survive a reboot.
