Landing lights are usually of very high intensity, because of the considerable distance that may separate an aircraft from terrain or obstacles.
Key considerations of landing light design include intensity, reliability, weight, and power consumption.
Ideal landing lights are extremely intense, require little electrical power, are lightweight, and have long and predictable service lives.
Additionally, landing lights have at times been installed as a vehicle high beam in the hot rod scene, although this is not legal.
Landing lights may not be lit when taxiing or near an airport gate; this can cause flash blindness to ground crew and other pilots.
