On my rig (1984 310 Limited) the red light near the key is a warning light for the levelers. Until I went through the wiring and the sensors on the levelers mine would go on and off at random.
To the right of my door (from the outside) I have the living room light switch, (hi, off, low), the porch light over the door (off, on), and the "scare" light switch (off, on).
