Looks like the new lights I just bought from Target are affected as well. I have the 100-lite, multi-color "Super brite" sets with white cords.
Those sets sell for around $2.00 each. I would say you get what you pay for, but:
I have many other strings from the same store which are over 4 years old and in near perfect condition. (All 100 lite minis.)
edited to add:
I do wish UL were more specific as to what the problems are. I have carefully checked out the ones I have, and they seem to be better built than the older strings I have. They also have enlongated bases on the bulbs with a wedge end that keeps the wire secured and the contacts separated. The cord insulation also seems a mite thicker than the older sets too. I'm having some difficulty seeing the problems here....
