will look for it,BTW,the thing that helped me make this suggestion was some
pages
on a MBZ website showing how to send more juice to the headlight,it did so by
taking the wiring that goes to the headlight,run them to a relay,then the relay
control an external source of juice (with big wire and fuses),that send a lot
more juice to the headlight,needless to say,it's a very popular mod to those
benz driver who regularly see life in triple digit !!!
