hi i carried out this conversion,i wired a relay triggered from the ignition feed to the dip lamp, so the dip stayed on when the main was used. yes there was an improvement but not nearly as good as a set of aux lamps see photo etc http://www.xt660.com/showthread.php?...t=bulbs&page=2 so i went dack to dip on/off as yamaha designed them and used the relay to power the spots off the full beam

just my opinion stoic
