The appliance to mark for machinery objects limits of passes has the element for marking the pass boundaries itself, it is arranged as a pole / rail with length not smaller than 1 m; at that at the outer surface of the element for marking the pass boundary color marking is applied. Additionally it has lower base, rotary node, system for light signaling, light reflectors, connection element and the node for fixation of the element for marking the pass boundaries to the connection element. The rotary node has power holder with power element fixed in it with possibility of rotation, the system oflight signaling has power source, electric lamps, connecting wires and control panel. The power element is placed in power holder at angle to the long axis of the power base, the plane of the power holder is placed either in normal position, or at angle to the long axis of the track of motion of themachinery objects. The connection element is fixed to the element for marking the pass boundaries either at right angle, or at any other angle with respect to the long axis of the element for marking pass boundaries named. The connection element is fixed to the element for fixation of the pass boundaries either at center, or at any other place, the power holder is fixed to the power base either at the upper part, or at any other place; the power base if fixed in soil vertically, or at any other angle with respect to vertical in the point of fixation. The light reflectors and the electric lamps are fixed at the element for marking the pass boundaries, the light reflectors named and electric lamps are placed at the elements for marking the pass boundaries either at its ends only, or at the whole length, symmetrically of asymmetrically one with respect to another, the element for the pass boundaries marking named. The power base and the connection element are arranged circular, square in shape or with any other shape of the cross-section, and the angle of installation of the power element in the power holder with respect to the long axis of the power base is chosen in between of 0 DEGREE and 90 DEGREE .
