Motion sensored lights

Sometimes my husband has to work at night and the house feels so empty. If anybody knocked at the door I'm not answering it. They should call first. I'm so happy with the extra lighting my husband installed outdoors. They're wireless outdoor motion activated lights that also have a little solar panel to charge during the day. The funny thing about it was  that the wind must have angled one towards the ground the other night.  I seen the light come on, I went to the window to see what it was and there was two rabbits playing in the snow. How funny.
