Apparently many find LED lighting less expensive. If you are going to get involved in the electrics, and because it has a less common dynamo, the Cornwall site article A Charging Refresher will likely prove helpful.
Many run their cars with the dyn and Field directly connected so permanent full output. must not be run without connection to system and battery. With ignition only load, should not charge much above 8 amps. Should not damage bulbs, but all systems will if poor battery connection.
