Yep, those are what I use. I do like the rather large retro lights they used in the 50's and 60's, but they don't really go with my tree. They also weren't selling the retro lights when I started doing my tree, but I do remember my parents still having a string or two when I was growing up.
My parents used the large multi -color lights pf the 50's/60's
