Review on Motorcycle Aluminium Handlebar Headlight Light Blue by Reginald Ward

As others have said the circuit has been broken and you have blown a fuse. I connected the switch to the Nilight wiring harness and it worked great! The colors of the wire harness were red, black and white, so it became red (wire harness) - black (switch), white (wire harness) - blue (switch) and black (wire harness) - brown (switch). So the light on the switch only came on when the light was on. The wires to the switch were smaller than the wiring harness, so we'll see if there's a problem or not.
