1. A system to change an operational state of one or more indicators, positioned on hydraulic equipment, to provide indication that the hydraulic equipment is in operation, the system comprising:
a hydraulic initiation lever positioned proximate an operator's seat of the equipment and actuatable to an active position and an inactive position, so that actuation of the hydraulic initiation lever to the active position is configured to cause generation of an unlock signal, thereby to enable hydraulic operation of the hydraulic equipment; and
one or more indicators connected to the hydraulic equipment and positioned to receive the unlock signal indicative of the operation when the hydraulic initiation lever is in the active position, thereby to change the one or more indicators from a first operational state to a second operational state in response to reception of the unlock signal and to change the second operational state to the first operational state when the hydraulic initiation lever returns to the inactive position.
