I'm with Andy, that's the scare (outdoor) light on my Trade Wind.
Also, don't let the turn knobs fool you. Yes, they are switches, but the one by the door also controls the ceiling light in front of the door. That way, you can turn it on when you open the door. Be aware that these are not double throw switches like in a house where you can turn the light on with one switch and off with the other and vice versa. When either
of these is off, the light is off
. It is nice, though, to be able to turn on a light before entering when you are in a dark place.
