Parking tower and underground parking are common parking ways in buildings, department stores, or malls. Gyrating parking lot exit shares the same road as entrances and exits;therefore, when we get to the exit, there might be some dangers, instead. Put five parking safety lights with infra-red sensor inside system for appropriate distance on the wall as patterns above. That is, for the entrances, the lights flash on the right hand;for the exits, the lights would be show on the left hand. The light will flash as warning with the closing car from the other side. More careful, more safety!
