The good news on this issue of proper cut off angle is that I just
found a site that sells a product which when used with HID replacement
lights suppibly provides the right cut off angle.

They are $25 per light, so you need two for a 2 beam system which
comes to $50.

But this would allow for the use of a standard 7" hella light with an
HID system.

I also found that there several sites that sell 7" round projector
lights.

I am planning to hit the car yards and see if I can find anything.

Scouring the web I found a couple of post from people stating that the
projector lens really improves the light projection even with an H4
bulb.
