Need info on DIY projection headlights

[GRNOVA]

This is what I am starting with:
They are real glass lenses w polycarbonate housings (I will have to get rid of the tri-bar)
Bulbs say: H4 12v 100/80W -non branded-
What I am striving to do is build a projector light by modifying this light if possible.
Pictures,links,past failures or someone who has succeeded in doing this all ideas will help good or bad.
