I take it you're talking about a mod you've seen somewhere? Wire it to your light switch, just make sure your total wattage isn't over 50.
You can expect 55 watts from a stock Blaster lighting coil.
Yellow/red from the stator is power.
Blue from switch is rear.
Yellow is high beam.
Green is low beam.
Black is common.
what color wires do i hook them up to?
i havent done lights before my blasty has no head light or tail light, thinking of putting wally world headlights on to, but i dont do much riding at night.
