I purchased a Dritz LED light bulb for my 401 at JoAnn's ($10.00). It didn't fit. Since I didn't keep my receipt, I ended up getting only 50% return credit for the bulb. I bought an old-fashioned bulb, which is the only one they had that fit. It is better than nothing. I'll order a couple of bulbs next time I order something online.
I would suggest you order online at
sew-classic.com.
