I haven't put a meter to mine (yet) - but my action is simular (lights up).
Ive been behind my dash SEVERAL times - mine is wired to
something.
the OTHER option switch on my dash (in close proximity to the one i cant figure out & my "road lamps") operates some "work lights" (aka additional backup lights) on the back of the coach (near the brake lights).
