Im no expert but seems like your probably going to need at least two on/off switches; one switch to turn off the headlight and the other to turn off the tail light. your front blinkers/running lights can be turned in to blinkers only, so you wont need a switch for those. to wire up the on/off switches, i guess you would find the positive wires to both your headlight and tail light and put an on/off switch in line. Someone else might have a more creative/expert way to do it, but thats probably what I would end up doing. I did something like that with a pair of LED's I installed on my bike. I have two on/off switches wired to each so I can turn one or both on/off (I used the positive wire from the license plate light so they only get power when the key is on).
