Hans to the rescue again! Yep, when 1 goes out, the rest stay lit. I don't have to replace the bulbs, but will keep my eyes open at any upcoming estate sales. I'll replace them only if I can find replacements on the cheap. The star will be hung on the inside, facing the street, so the flaking bulbs shouldn't be too noticeable.
The helpfulness on this site is unbelievable. Thanks again!
