We have two homes and purchased lights from Wal-Mart years ago and they have worked beautifully at our home near the coast. I bought four sets of these lights and they work maybe a quarter of the time and only half of them will work at any given time. I am going to try to contact the vendor to see about replacement lights, but as most do not work at any given time, several have been run over because we could not see them. Pros: None Cons: Waste of money!
