1. A method to change an operational state of one or more indicators positioned on hydraulic equipment to provide warning that the hydraulic equipment is in an operation mode, the method comprising:
initiating a power-on status of a power source of the hydraulic equipment; and
actuating a hydraulic initiation lever from an inactive position to an active position, the hydraulic initiation lever positioned proximate an operator's seat of the hydraulic equipment and proximate hydraulic operation controls, the hydraulic initiation lever connected to a fixed location within a hydraulic control box and connected to an additional lever, at least one of the hydraulic initiation lever or the additional lever to prevent entry and exit into a cabin of the hydraulic equipment when the additional lever is in the active position, the additional lever to depress a switch when the additional lever is in the active position, the switch connected to the power source, the proximate hydraulic operation controls, and one or more indicators, the switch includes a circuit between the power source of the hydraulic equipment and the proximate hydraulic operation controls when the hydraulic initiation lever is in the active position, thereby to activate the proximate hydraulic operation controls, and the switch also includes a circuit between the power source of the hydraulic equipment and the one or more indicators, thereby to cause the one or more indicators to change from a first operational state to a second operational state.
