this is the same type of front brake light switch i have.
underneath most pitbike bfront brake levers, there is a cutout and screw mounting hole there.
this switch screws on and you run a wire from positive power and the other wire goes to the brake light. http://www.ebay.com.au/itm/BRAKE-SW..._Parts_Accessories&hash=item2576d4fe28&_uhb=1
