Helicopter Night Vision Lighting. Night Vision Goggles (NVG) provide an awesome capability for the pilot/observer to "look" outside the aircraft at night. This vision permits a pilot to fly closer to terrain & perform safe landings & takeoffs along with provide covert surveillance. The NVGs are sensitive to infra-red (IR) light which comes from the stars & moon. The IR light reflects off the terrain & is "observed" by the NVG's.
Cockpit lighting enables a pilot to see his instruments & radios at night. Cockpit lighting, though, emits predominantly infra-red light itself due to the fact it's usually incandescent. Incandescent lighting emits more than 90% of its energy in the IR range that the NVG are sensitive to. Result, the NVGs are blinded by enormous quantities of IR present in the cockpit since they are created to pick up nominal quantities of IR at a distance. So, regular lighting is not compatible with employing NVGs since they're sensitive to even the dimmest standard cockpit lighting.
NVG aided flight operations originated during the Vietnam era & evolved for many years with increased use by typically military operators. The technical quality and abilities of the NVGs improved steadily & began to receive interest from other sectors of aviation for its improved safety and operational abilities.
In the late 1980's & early 1990's civilian operators started doing operations with NVG goggles and a large number of would turn off the aircraft lighting or tape over light sources that could not be turned off or dimmed. Today, NVG aided flight has turned out to be commonplace among military and civil (primarily first responders) air operations. There are a variety of cockpit lighting solutions available. See "Cockpit Lighting Tradeoffs" for more information. There are also rigorous regulatory standards that govern civil NVG air operations. These standards are regulated by the FAA, EASA, and other regulatory agencies worldwide.
