Below are two svg's that could be used as lighting path graphics. I will be creating more later today, but these are the first two. Hopefully bast decides that incorporating lighting into one tile paths is feasible.

These are the simple paths, so they get simple lanterns. The stronger and more eficient paths will get more complex lights and should also cost more power than simpler lighting tiles. Each road will either have lighting in the floor of the road or on the top corner. This is because rovers are going to move over anything that is placed in the other three corners.

Let me know what you think.
