Actually, I have such a laser in my drawer, don't know how small the operating part of it is. I have a laser level and tape measure, I got it years ago from a friend of my wife's that sold Avon produces of all things. The box is even labeled Avon.
In looking, I'm not sure where I'd put it on the Phantom, the nose is pretty busy as it is, it has the headlight, MARS light, and the turbine inlet that I put a couple of flickering blue LED's in. The lower pilot skirt has space, but not much depth without interfering with the front trucks.
Interesting idea, I'll have to look around for a compact solution like that.
Edit: I didn't have to look far!
