I think this was great info overall but we jumped far off topic so Ill try to close my point with this lower voltage option that Im believing will work for my purpose.
The fact is the LED headlight still is a myth because of intensity, range, and color issues;
DOT here in USA has not approved them.
"angel eyes and others are more ambiance and dont effect night visabillity much."
The ones listed are infacto driving lamps, and fog lights.
They will work well for my purpose, and will be usefull for keeping alternator calm and quiet mostly.
