Without using the other wire there is no ground and the headlight will not function. The headlight has to have its own ground to the frame to work. The hub only grounds itself to the frame by making contact on the inside of the dropout. The same goes if you setup a taillight. This is easier because the wiring harness has the wires already setup for this.
