Is it possible to make a layer illuminate another layer like a light?

I have layers that are compositions where I'm using the stroke effect and the glow effect - so it looks like it's some sort of lighting (like flurescent light or something).

So I've placed qutie a few layers of those compositions as layers in a new composition in 3d space, as though they are stood up. I've also created a long floor flat solid that goes under them.

Is there a simple way of making those layers illuminate the floor with whatever colour of "lights"  are in the layer (ie. what was   just done with the stroke and glow effects)? Like a reflection of the lighting on the floor.

I know some tutorials suggest to duplicate a copy of the layer and rotate/flip it so it's on the floor but that's not going to be that accurate (and it should really be lighting up the front, back and sides of the part of the floor where that layer is).

Also the 3d camera will be moving forward in 3D space so what might look okay for a static scene (eg. just creating a flipped version of a layer for a reflection) may not work as well when the camera is moving forward. Also in the precomp the stroke effect is moving - so that would complicate things if trying to add the reflections using real after effects lights.

edit: I've attahed an image to show what I mean. I've added some real After Effects lights but I really want it to seem like the layer (precomp that's made with the stroke and glow effects) is lighting up the floor.
