Abstract:
A self powered spheriacal marker is mounted on a power line by extending the line though opposite openings in the marker. There are two sets of opposite openings to allow the marker to be oriented so that solar cells mounted on the exterior of the marker face a southernly direction. A battery inside the marker is maintained in a charged condition by the solar cells and power led lights that flash intermittently so as to draw attention to the marker. Two halves of the marker are secured together by pin-latch fasteners that are placed around shoulders extending around the periphery of the marker.
