On the way to work this morning got a rear brake light out message on the DIS, carparked up in thecar park and partner got out and checked and it seems the BLS compensates when you lose a buld by making one of the other light work in it's place ! !

Got home tonight and remembered I had a bulb kit so set about replacing the left rear brake light total 25 secs ! easiest car I have had for doing the rear lights
