Just curious why the big deal about a light burning out? They are inexpensive and easy to replace on every machine I've ever had. I leave my machine on most of the day if I'm sewing. I always turn it off at night, when leaving the house, or if I know I've finished for the day. The only time a light burned out on one of my machines was on a 1962 Pfaff that had been in regular use for over 30 years. I think the bulb cost around $4.00.
