iwant to add just a headlight to my bike. everywhere i look i get told something different. i get told i need flywheel weights or a different flywheel. the only kits i can find has taillights and blinkers and i dont want that crap. can i just buy a moose or electres light stator and a regulator,and light without having to change flywheel or add weight to it. will i have trouble with the light not being bright enough?
