USB Light Storage allows to see necessity also to read books to everybody and anywhere.
Nearly all around the world owns any produkt with USB and with batteries inside.
Sometimes the others would like to have light switch off(in any vehicle, waiting area, sleeping area, music clubs)..so can use own ULS.
Inside ULS cable is hard wire which allow to hold position.
Switch on/off button is under the elastic surface near the LEDs.
