Abstract
Techniques are disclosed implementing a lighted guard system, which changes from one color (e.g. white) when the guard is down (i.e. closed) and/or a machine associated with the guard is operational, to another color (e.g. red) when the guard is up (i.e. open) and/or the machine associated with the guard is not operational. The triggering of the change in state of the guard may be facilitated by a switch that changes state based upon a position of the guard.
