Not really an issue just wondering really. The RHS (mpg) of the message center is reasonably bright but not as bright as the LHS, as I set off the RHS gets duller until it's unreadable. Next day it's reasonably bright again and so on.
I've no idea what or how this is illuminated but I want to find out what needs fixing if or when I remove the binnicle in the future.
TIA.
