As reported here at the time, my light switch on the 2014 4/4 was broken in summer 2015. It is the same model. In my case, it was precisely on the light switch that rainwater dripped and made its way through the frame of the soft top on the windscreen. A thicker layer of insulating rubber in the frame of the soft top stopped the raindrops and the new switch has now lasted for 8 years and 110,000 kilometres. The light switch is electrically relieved since I have LED driving lights.
