So... if you tie the two blues together at the key sw. it will function just like GLJ says his does.
Pos 1 and power to the tailight will come from the handlebar sw.
Pos II the key sw. will back power the handlebar sw. You can either put a diode between the two switches.... or just remember to turn the headlight off when in pos.II
