Light render issue at distance

Hello,

I'm not really sure how to describe this issue, but if you look at the images below. The first image showing a model with lights on inside, but the second I walk backwards only slightly and then the lights turn off. I'm not sure if this is a rendering issue. In short, only when I'm in certain range of the lights do I see them on.

I've tried enabling disabling fog, increase / decreasing clipping on the main camera, increasing the quality settings in the player section. I've also tried increase the amount of pixel lights rendered.

I have one directional light in the scene, and two spot / point lights within the cabin.

I'm not really sure what to try? Maybe someone can offer a simple suggestion.
