All evidence points to the light is under software control. Indeed,
I believe UMax's software for Windows for some of its less expensive
scanners includes a desktop applet that lets you turn the light on
and off manually.

Some people claim that their scanner will scan transparencies even
though the film isn't back-lit. I wonder what would happen if
you back-lit with an ordinary flourescent with a diffuser.
I'd need to dig to find some microfiche.
