Overhead wire marker

Overhead wire markers are safety instruments applied to the overhead power lines marking transmission lines and ropeways along the flight path during the day.^{[1] [2]}

Markers are often installed on overhead lines near airfields, or at river crossings where there is a possibility of seaplanes using the river. Some markers contain conductor marking lights or strobe lights to improve visibility at night or in fog.
