If you want to change how sharp the cutoff is I highly suggest changing the lens  Easy few screws to swap them on/off if you have the headlight apart, and makes a world of a difference. These STI-R clear project lenses were ~$60 iirc, and it sharpened my cut off a loooot. Top being stock, bottom being after the lens swap. Same bulbs and ballasts and evertyhing on the projectors from my 370z. Bulbs apparently make a slight difference in cutoff too  |
Good clarity lenses make a large difference in a sharp cut-off and also will generate that blue tinge you see most commonly in high end cars (think mercedes or the likes). This is where replacement lenses from TRS come in (like the common TSX-R lens swaps or FX-R lens swaps).
The bulb impacts beam width, pattern and cutoff.
Cheap bulb with most likely a shitty pattern, spread and cutoff:
Quality bulb (arguably the most expensive and highest quality bulb available, Osram CBI, this is the factory bulb in most high end German cars):
The most apparent difference between the two bulbs above is the metal stabilizers on the quality bulb instead of just a straight plastic base. This setup allows for a wider spread.
My current headlights on my FX have had the FX-R lens swap, and while the headlights were open, the shrouds/lenses were adjusted and bent to make the optimum cutoff and maximize the refraction of light at the cutoff (Purple/blue tinge at cutoff, this means that when you see my car bouncing down the road over bumps it fades from a really crazy blue colour to an almost complete white, its a really cool effect).
It is underrated how difficult it is to get a good cutoff, my pattern looks much like the one posted above by kakucaekz. Which is pretty much as good as I have seen on any car.
