It's worth a bit of your time to check out the HID Planet forum. Putting HIDs in a reflector headlight makes for uncontrolled light scatter which glares into everyone else's eyes on the road. You about tripled your light output and halved your control of it. It's pleasing and entertaining to the person in the vehicle with the HIDs in the reflector lights, but blinding to oncoming drivers. Enough so that it can cause them to loose sight of the road surface and go off the road, especially outside of town in dark areas.
I'm in Socal and both you and I see many people with HIDs in reflector headlights in town. On a big wide, well lit boulevard, it is just irritating to oncoming traffic and in rearview mirrors of people in front of you. On a dark, narrow highway, it could be much worse for someone. Some things to consider for your fellow drivers that share the roads with you. It's a hazard, and it's real. Just because a lot of other people do things, that isn't justification to make it the right thing to do. Man up.
