A passive defense system that utilizes a plurality of high intensity visible lights to reduce the number of targets in view of attacker(s) or aggressor(s) and to disorient and possibly incapacitate the attacker(s) or aggressor(s). The defense system includes a plurality of high intensity light sources controlled by a control system that can be activated by physical switches, by a central control station, by remote access, or even automatically by a gunshot detection sensor. The light intensity, placement of lights, and strobe effects produce a system to deter or defeat armed attackers or other aggressors.
