caption_attribution_description: English: An aviation obstruction marker on a high-voltage overhead transmission line, near Lyncrest Airport, Winnipeg Canada. The marker reminds pilots of the presence of an overhead line which would otherwise be difficult to see.
context_page_description: Overhead wire markers are safety instruments applied to the overhead power lines marking transmission lines and ropeways along the flight path during the day.
  Markers are often installed on overhead lines near airfields, or at river crossings where there is a possibility of float-equipped aircraft using the river. Some markers contain conductor marking lights or strobe lights to improve visibility at night or in fog.
