Directional/ Linear, point, direction light not working in final rendering screen

When I have my drawing in the normal render mode in the screens the light shows, but when I am trying to render in the final render screen it doesn’t. Can someone please help.

I’m not certain but are you asking about seeing a bright spot in the actual rendering where a light is? Can you post a 3dm file and any screenshots or renderings to help explain? Also, what version of Rhino are you using and with which renderer or display mode?
