I find this thread kind of funny. I don't have any replacement light bulbs for my machines, and I did blow one a year or two ago and it took forever to find another one, had to special order it. The funny thing is, so many of us don't have a spare bulb, but do you have spare lightbulbs for in your house light fixtures?? Then, I ask, why don't we have spare bulbs for our machines???
I have spare needles, serger blade, spool holders, but no light bulbs. I think that will be on my shopping list.
