This item didn't even last for a month. Such cheap products sold by Amazon. At least they should check the durability of items before selling it here. Also, it was not that cheap. Local market and light shops have cheaper and durable lights. Think twice before buying the product.
The lights got spoilt within a few days of being put up, and that was when no one was home for most of the time. They weren't touched or manhandled either. Just a very randomly short life and a waste of money.
