What year is your Bird as the later ones have a flat dipped beam and don't need a converter.
Two ways to tell, take a look through the front , is there a flattened area on the RH side (as you lok at it) ? Yes? it has a kick to the dip.
Second way , park bike in front of wall and turnheadlights on, do you have a flat topped dip beam or does it kick up to the left?. If the former then no converter required.
