If wet is getting behind the instrument panel, it needs to be sorted immediately. However, this is unlikely.
My theory, water is affecting one of the sensors listed, but the instrument panel has a poor connection or earth, causing the bulb to flicker. Or the warning bulb is about to die, causing it to flicker.
