Solar Aviation & Navigation and Obstruction Light

The light systems used for airports, runways, obstructions, and other visual aids at night are other important aspects of night flying.
Lighted airports located away from congested areas can be identified readily at night by the lights outlining the runways.
Aviation lights are designed and installed in a variety of colors and configurations, each having its own purpose.
Obstructions or areas considered hazardous to aerial navigation are indicated by beacons producing red flashes.
