You can choose between an LED or non-LED scoreboard. A non-LED scoreboard is made with industrial-grade aluminum. You may record the number of injury-free days using water-soluble markers or magnetic number cards.
On the other hand, a LED safety scoreboard needs a direct power supply to run. It includes a remote control that you can use to program the numbers appearing on the LED counter display. Depending on what you need, some LED signs have color-coded lights (typically green, yellow, and red).
