Seller was very quick with a reply to my question that the lights were not turning on during darkness, only daytime. When there is sun is shining during the day, the lights will generate electricity, because the switch is not turned on, the electricity goes directly to the lamp beads, even though its daytime, and the lamps light up. So you need to push the switch so the lights are off daytime and then the power is stored and the lamps come on after dark. I use these on an motorized driveway gate so it is marked well when opening and closing.
