I have the stick-on one from Nancy's Notions. It's nicely bright BUT it doesn't want to stay stuck on! My machine has no completely flat surface to stick it to. It will stay for a bit then fall off. So, I taped it on. Needs more tape. If I get the light shining the needle area properly, the thing is either in my way & I can't see to sew or I bump it constantly when moving my quilt around. If I ever get it properly positioned...it'll be great!
