According to the Federal Aviation Administration (FAA) standards, portable runway and taxiway lights and runway end identifier lights are for temporary use to permit continued aircraft operations while all or part of a runway lighting system is inoperative.
Portable lights are for use only on a temporary basis and are not suitable for permanent use. They are intended primarily for visual flight rules (VFR) operations. Where portable edge lights are used to identify the runway threshold, they should be supplemented with portable runway end identifier lights to improve runway end definition. Portable lights must be securely anchored to withstand wind, wake vortices, and propeller/jet blasts.
