Strobe lights create a spooky Halloween atmosphere all by themselves, but when you add spooky sounds you get another element to increase the fear factor. The LED Strobe Light Box with Sounds is small but very effective. The box is 5 X 5 inches wide and can be put anywhere. Since it is battery operated, you can carry it from room to room without the fear of tripping over cords. This strobe light box provides bright white light, and because it is LED it will last for years.
