| Signs are reflective. Both the vacuum and electric models will flip out when you trigger them, and the lights will alternately flash. You can choose either electric or vacuum powered signs. These swing arms are designed with the highest safety standards available and are manufactured by the same company that supplies school busses nationwide. From research done on buses, it is a proven fact that swing arms save lives. If they are not required by law in your area, we highly recommend them to keep your customers as safe as you can when they cross a street to get to you. Prices include hardware such as the pull knob to turn sign on, and flasher. |
