Yamaha use a standard H4 bulb. It's the geometry of the bulb that gives the angle between main and dipped beams, not the design of the reflector.When the lows are adjusted to where I like them, I find the Highs too high as well. If the highs are adjusted just right, the lows are too low for my taste. One would think Yamaha would have adjusted that over the years (the lights that is)....

Reflector design will only change the spread of light, not the difference.
Yes there is..... however the majority of people think that setting on lows is too low (including myself). Yamaha put too much difference between low and high. If you use the recommended setting, the lows are too low and the highs are good. There is no good compromise with both lights set the same. The solution I suggest is adjust low beams to that setting then raise them both one turn of the adjusters. Have someone ride in front of you in daytime a few hundred feet ahead and let you know if your lows are look dim (i.e., at 500 feet say, you're not that "visible" and your lows look like parking lights). They should be set just to the point of being almost full brightness, and you are 'visible'. At night, this may be slightly annoying to oncoming traffic, maybe not, but you might be of the opinion it's not good enough. So now lower the left a half to one full turn of the adjuster and raise the right a half to a full turn. Check against the mark on your wall so you know for next time. Now at least you'll be seen better in daytime by oncoming traffic and have decent lighting at night. Tweak on future rides if necessary. This is the only compromise that works for most of us who do not do a lot of night riding, otherwise, you'll want auxiliary lighting. Oh yes, and change out those stock bulbs for something a tad brighter.
Redfish, set the electric adjuster knob in the middle, then go under the bike and adjust the headlights (where you want them) with the manual knobs on the headlights. This leaves you a bit of up and down with the electric adjuster. And if you still have those OEM 45 watt bulbs on the ST, ditch them (they are unique, so you have to cut tabs/use a spacer adapter to use H4's).
