Do you leave lights on for your dog if you go out at night?

When I go out and leave my dogs at home, I leave a light on, too. The light I switch on is outside the house. I don't need any lights inside the house because my dogs are fine with sitting in the dark. The light outside is for them to see better anyone who's in front of the house. And of course, the light is for me, too, because I cannot see very well in the dark.
