If I switch dynlights off then externally the aircraft is still lighted but not as much as with dynlight On. Virtual cockpit looks pretty dark with dynlight off which is what I expect. If I switch dynlight On then the cockpit it very bright. To me it is too bright but may be it is supposed to be like that. I jumspseat in the cockpit time after time so I know how the VC looks at night. To me it is a bit bright with dynlight On.
