Beschreibung
Zusammenfassung:	A component is for an electric power system. The component includes: a user access panel; a first element for directing visible light; a second element for directing visible light, the second end of the first element facing the second end of the second element; a movable conductor structured to move between a first position and a second position; and a stationary conductor structured to engage the movable conductor. In the first position the movable conductor is disposed between the second end of the first element and the second end of the second element, thereby blocking visible light from passing from the first element to the second element. In the second position the movable conductor is not disposed between the second end of the first element and the second end of the second element, thereby permitting visible light to pass from the first element to the second element.
