Weird Lighting Problem

![alt text][1]

I am experiencing a very weird problem here.
When I add any light to the scene, everything is ok till till I add 2 lights. But on adding the third light, everything goes weird.
This happened with both point light and spotlight.
I have screenshots of the scene here.

I am very new to unity. So this may be some very silly mistake of mine that I’m not able to see.
Please Help


This happens because one of the lights is being evaluated as a vertex light! There are a few ways to fix this- you can either increase your quality settings to allow more than two pixel lights, or you can manually set the lights to ‘important’ so that they override the quality settings.
