Formation Lights (Brightness Knob)

[Leadnap]

I know its a super minor issue, but probably easy low hanging fruit if someone has an extra hour or two to hit the code - the Formation Light Brightness knob which has three functions doesn't do anything. The formation lights don't change externally.

 

Would especially be nice to have though since the Form Lights also light the tail for unit reference which is incredibly visible in low light at a distance (the exact opposite of the rationale for having formation lights, and why probably real estate in the cockpit was dedicated to such a knob IRL).
