Re: 12 volt fog lamp as headlight
All of these suggestions use batteries. Does anyone know of a light that can run off of the engines generator. If not, what is the generator wire for? Perhaps two 6 volt batteries wired in parallel to the engine and in series to the light could act like a capacitor preventing the engine from losing a spark and allowing it to charge the batteries during daytime riding. Using the right resistor would also allow the generator to increase the battery under a load without killing the spark.
Though that would be a lot of trouble if there are 6 volt lights that could be used instead.
