At entrance points, light should be intense
enough to enable guards to identify bearers and badges.
Control of the
lighting must be with the security forces.
g. Interior and exterior arms storage lighting must be provided.
Included are buildings where arms storage rooms are located, motor pools, and
Also, outdoor parking areas for vehicles or aircraft that have
weapons stored aboard are included.
Unauthorized persons must not have
access to switches for exterior lights. Wire mesh screen must be placed over
these lights. This will prevent their being broken by thrown objects.
Principles of Protective Lighting.
a. Security forces should be able to watch activities around or inside
They should be able to do so without disclosing their presence.
Protective lighting should be used in conjunction with other measures.
Examples are fixed security posts or patrols, fences, and alarms. Do not use
to see low contrast. This vision is improved by higher levels of brightness.
b. In planning protective lighting, high brightness contrast between
intruder and background should be considered first. Dark, dirty surfaces or
camouflage-type painted surfaces require more light.
c. To be effective, protective lighting should:
(1) Discourage or deter attempts at entry by intruders.
(2) Make detection likely if entry is attempted.
be used will depend upon the overall security requirements of the post/area
(See Table 2-4).
There are four general systems of protective lighting;
these are continuous, standby, movable, and emergency.
a. Continuous light (stationary). This system is the most common. It
consists of a series of fixed light fixtures arranged to flood the area.
Flooding is in overlapping cones of light during hours of darkness.
Continuous lighting is used in two primary methods: glare projection and

This method makes it
hard for the intruder to see inside the area.
It also allows the guard to
watch intruders at great distances beyond the
