Realair Sf260 VC very dark at night

Hi.  As per the title, the plane works fine in v2.1, it's just that at night the VC is so dark that the instruments are unusable (this is with cabin light on).  Also, while the cabin light does work but is nowhere near bright enough, the instrument lighting doesn't appear to work at all.

Just hoping someone might know of a workaround.  Thanks for any suggestions.
