The Department of Homeland Security is funding the creation an LED flashlight that uses powerful flashes of light to temporarily blind, disorient and incapacitate people.

Homeland Security’s Science and Technology arm hopes government agents can use the “light saber” to arrest people on planes and at the borders without using traditional weapons.

The LED Incapacitator uses a range-finder to measure the distance to a target’s eyes and then unleashes continually changing, multi-color light pulses that both blind and disorient the person.
