Protective lighting provides a means of continuing a degree of protection from
theft, vandalism, or other illegal activity at night. Security lighting systems should
be connected to an emergency power source, if available. Requirements for
protective lighting of airports depend upon the local situation and the areas to be
protected. A careful analysis of security lighting requirements should be based
on the need for good visibility and the following criteria: employee recognition
and badge identification, vehicle access, detection of intruders, and deterrent to
illegal entry. Protective lighting is generally inexpensive to maintain, and when
properly employed, may provide airport personnel with added protection from
surprise by a determined intruder. However, when developing any security
lighting plan care should be taken to ensure that lighting does not interfere with
aircraft operations.
