Just aim HIDs a little lower than stock lights and they will still give you better vision without blinding anyone. I have HIDs on my VS, without projector lamps (though I am in the market for some if anyone can find me some to suit a VS
) and I don't get flashed so I assume my lights bother no-one, and the cops don't look twice. Its not as if the car isn't noticable lol they all take a second look, but not at the headlights
Even if you get projector lamps though, to be genuinely legal then you must also have self levelling.
Another option is to only fit HID to the high beam, and leave the high/low beam as a standard H4. You can add better globes to the H4 instead if you like. If your state requires regular inspections though, you are still going to have to stick standard globes in both before you get inspected.
