i kept the mag and fitted an alton with a toothed belt, i now have really good lights, and its much better than the low wattage 6v led stuff , tried that first there are some really god led's about for 12v but they do need a bit of power, i do ride a fair bit at night and live in the middle of nowhere on crap roads, so good lights are a must. i am going to convert my sq4 to an alternator as that is really crap at low speeds,
