S-Light / Rescue Tools


When you need to send a signal.(like sos).sometimes you may use the flashlight.
But Light is hard to control the direction.The idea is push an Aiming mirror in the flashlight.the flashlight use the LED,a new techonology named LIFI(LiFi--Light Fidelity) can let the LED send signal.So just say sth to the “S-Light”,then aim to the target which can receive the signal(like Helicopters/Ships...)
Finally ,push the “S” to send the signal.
