An electrical component for an irrigation system is provided wherein at least one electrically-switchable optical element is disposed in front of a visual indicator such that in the absence of electrical power to the electrical component the electrically-switchable optical element obscures the visual indicator behind it. This provides a visual means for quickly identifying when power to an electrical component of an irrigation system is interrupted by obscuring one or more visual indicators that would otherwise be visible. |
