Do you sleep with the light(s) on or off?

I can sleep anywhere, so whether the lights're on or off dont bother me. However, when I'm at home, I HAVE to turn off the lights before I sleep, just because I cant sleep as I feel as if something is incomplete and wont be able to sleep till I do it (same with brushing my teeth). That being said, I wish it wasnt so, as I usually read on my bed under my blankets (especially when its cold) before I sleep, so its really a hassle to get up, walk over to the door and turn off the lights (I wish I could set my phone as a remote control for the lights >_<).
