I have HIDs in my car.
What I did was parked on a very dark back road and put my car in park.
I adjusted my lights to where I could see about 50-60 feet out.
What's sad is that I don't know if my HIDs make it seem like I have high beams on or not, but I do know that when I turn on my high beams that there is no damn difference in vision gains. I haven't had anybody flash me or anything yet, but I was only about to drive my car for about 3 weeks before I deployed.
If I notice HIDs in a car and it's slightly blinding me I just look past it because I'm doing the same thing and it's not like it's intentional. I just don't want to realize I'm about to hit a deer when my lights only shine 20 feet in front of me.
HIDs are the way to go, but if you got the $$, get projectors. One day after a turbo I'll get them.
