Question: How many sets can you string together?
Document: Great lights but way too little lights. Should've had twice as many lights for the money. Looks great on the lawn especially when it is covered with snow.
lights are just fine the only problem is I only bought 4 sets in case I didn't like them and when I tried to get more there was no more available with no hope of getting more,  I don't know why  blue lights with green wires are so hard to come by
Super bright and they give off a black light effect on UV and neon colored surfaces. I ordered three boxes and none of them had replacement lights, which was a pain since I had a light go out within a few weeks of usage. The one light being out isn't that noticeable because you get so many lights to one strand. I will admit that my porch looks a bit like an alien spacecraft from a distance. These lights really stand out and can be seen from very far.
This is a superbly constructed set of icicle lights. They even include protective connectors with O-rings to protect contacts from moisture (glitch 1: these connectors prevent other strings with a standard plug from being connected to the end of these strings).Glitch 2:  When you order this item, despite the description, you may get either white wire or green wire (If you look at the alternate picture provided for this item, you'll notice both are shown).
Good value for the money, but could use a little more lights per foot. I'd buy again however. Merry Christmas
Exactly what I was looking for and thank you for sending so quickly. They lool beauiful out side. Thanks again
