I cannot sleep even if there is small light in the room

Can you sleep with lights on?

I usually switched off the lights when I go to bed. If I am really tired and sleepy, I can sleep even with the lights on.

Yes, but I prefer to sleep with the lights off. When the lights are turned off, I can sleep soundly and peacefully.
