I have an Email class W212 estate and my question is. Is there any way to get the instrument lights (Speedo rev counter etc etc)to be permanently on as mine will only come on with the side light position on the light switch or when the auto lights turn on. It is some times difficult to see the dials but clearly not dark enough for the auto mode to bring them on. I have also noticed that the headlights/instrument lights come on first followed by the radio and heater controls as the night gets darker. All my other vehicles have the dials etc permanently illuminated. Any suggestions
