I, too, worry about the light burning out on my new Brother 450Q. And I can't turn it off -- I think -- without turning off the machine, which means losing my settings. So I leave it on when actively sewing, as in when I sew, then press, then sew. Otherwise, I turn it off.
My Golden Touch 'n Sew no longer has an active light in that we had to replace the light holder and it just does not work, for whatever reason. I use an Ott light which stands on the machine cabinet when sewing on that machine. But I also worry about burning out the Ott bulb, so turn it off when not actively sewing. I'm a lights off kind of person, though; I turn off lights when I leave a room (except the kitchen, for some reason; I'm always going back in there, maybe!).
Interesting topic. I've enjoyed others' points of view on the sewing machine on/off and the light issue.
