It too hard for me let's the picture explain you what i ve found hope this can help anyone who try to make their headlight more brightness also white not Yellow
this pic will show you how different between 2011 Jap Ver and 2012 US Ver
So now i made a lot of kind of smd burning now i have found the right smd for L strip
to compare with 2012 US ver my mod make 2012 US get yellow more
now when we take it to the car while ig on position the Voltage will be 13-14 v, that could make ur led get burner so i use this device to control voltage input does not come over 12.0V with adjustable volume
waterproof DC/DC Converter Regulator DC 8-22V Step DOWN to 1-15v adjustable
Lets see How it work i choose to control only L Positive coz SMD LED will get burn on this
I Dont know Japan Lang..
