I had planned on roof mounted front and rear floodlights, already have them in my shop. Maybe I can just go with that, since my brain can't figure out how to make a retractible cover that would look decent coverd and uncovered, and not make so many holes through the front. I guess I could have both on each side be amber blnkers but that seems a bit rediculous. I'd just like to preserve the look and have it be functional as well.
Roof (and side) mounted floods could be made to tilt, so hopefully that would be sufficient. Also, what natster said, a solid lightbar could be useful. I'm guessing it would need a cover as well.
So much for my idea of making a locomotive looking over & under setup in the middle of the front at the top like this:
