The Emergency Airfield Lighting System (EALS) is a runway lighting system designed to be quickly installed at contingency airfields or at other locations that need temporary airfield lighting. When installed, it provides runway edge lighting, approach lighting, threshold/end lighting, taxiway lighting, visual glide slope indication, Distance-To-Go (DTG) marker lighting, and obstruction lighting.

The EALS can be installed and deployed on all types of surfaces (e.g. sand, frozen earth, mud, ice, asphalt, and concrete) and can light a Minimum Operating Strip (MOS) of up to 150 ft. by 10,000 ft. Installation of a 50 ft. by 5,000 ft. MOS can be done in only 2-1/2 hours by a six person crew using two general purpose vehicles.
