Lighting Light Increase

I’ve multiple lights in my scene, but I don’t want them to STACK on each other (in other words brighten each other up.) I want the lighting to be constant, and not get increased because another light is overlaying it.

I’m using this for a RTS game in which there is a FOW and the light is parented on each unit acting as a FOW light.

One thing you could do is instead of using a lightsource, you could create a texture with a gradient on it, and have a plane with that texture on it simulating a light.
