At this Christmas Lights we have all a lot of joy. Previously you had to rely on lights on the length of the cord, if you wanted to install the candles on the tree and then the strings between the branches did not look so decorative, and they needed an extension to the socket. The wireless light string can attach the candle where you want, you can omit that or even add buy some. By clicking go all the lights on and flicker like candles, at repeated switching them to flicker less and when you press, they light up without flickering. The batteries should last, depending on the use for several weeks. You can still use other decorations for the candles after Christmas to drain the batteries. After that they should be removed before kept the candle for the next festival.
