Hide lights for other camera(s)?

Okay, i have 4 cameras rendering at the same time. and i have 4 spotlight.

I want camera 1 to only render light 1 and not light 2,3 and 4. then i want camera 2 to to only render light 2 and not 1,3 and 4.. and so on. basicly each camera should only render its own spotlight. But they all render all the lights.

Using layers and the camereas culling mask does not work. and i cant find any answer to this exact question anywhere.

How do i make the cameras only render their respectful light?
