I have been thinking about doing something like that to the snake eye lenses myself, but it would invole lots of custome work, and im not sure how I would want to control them yet, but im thinking of wiring them with the side marker lights, that way it would simplify the install and also allow some control. And I was tinking of just using some sort of LED bulb (maybye 2 per lense) ... So, ill prob be looking more into that late this summer, after summer semester ends and im bored.
As far as projectors go, i feel like ive seen it done once (shoddily) but it would look good if done right, I just wish there was a kit for it.
