Is it possible to use a 12 volt fog lamp as a headlight or would that just be a waste of time. My buddy bought a set and we tried them out and they are super bright! We want to use them as our headlights for our bikes but we don't want to have to mount a battery. Don't want the extra weight. Anyone have any good results using the magneto to run them? If not any good headlights for under 40 bucks that anyone know of?
