Last January, I was walking the dogs back to the 5er after our usual morning jaunt, and thought "what the heck is shining on the trailer??". I'm guessing Ed tried to hit the interior light switch the night before, and got the scare light switch, instead? Since we never had those on our previous Class C - we never thought to use them anyway....
I normally never leave any outdoor lights on - I'm a Dark Sky sort of girl :-) And long ago, I learned it was easier to walk and pick up after my dogs, if I was wearing a headlamp; so I have those stashed everywhere.
