Part of out bathroom renovation includes taking out a light soffit with fluorescent lights and replacing with vanity light. Our dilemma is that each wall/mirror is a different size. There is electricity above each mirror, so we can do up to 3 lights. We are planning on keeping mirrors.

Our questions are:
1. What size light Above each mirror, and if each one should be same size, or smaller light above two smaller mirror.
-if doing smaller light, it would have less bulbs, would this look silly

2. Put a light over each mirror, or just over sinks. We have overhead lights as well, so they are not the only source of light.

Thanks in advance for your thoughts!
