ABSTRACT:
A light that meets Federal Aviation Administration requirements for marking powerlines or powerline support structures that is powered from the magnetic field created by the conduction of electricity along a powerline. The energy in the naturally occurring magnetic filed induces an electric current in a specialized coil within the device that delivers a constant voltage to a lamp. The lamp is focused through a lens into the beam pattern required for marking powerline support structures.
