Here's an update on what I am doing: I have a little ways to go to present a complete lighting solution for lawn mower type engines. It is not a low cost solution, but it is designed to supply about 92 watts, a little more than the whizzer motorbike at 12 volts. This means auto lighting and a halogen front headlamp can be used. This system will not fit every bike, and some reengineering of your set-up is required. The solutions makes what is now a novelty that can not be legally ridden, into a street legal moped that can be licensed and driven anywhere. I will provide complete pics after I patent the solution. It is taking time because I have had to solve or develop both mechanical and electrical solutions. Forget about white wires and the mag. There is no low cost, easy solution to this problem. Mike S
