the dash cluster is fitted with back lights, cost pennies to replace. remove the facia using a wide blade scraper be careful not to mark the aperture. then remove the cluster using a torx bit screw driver, 4 screws one in each corner. then ease out the cluster and disconnect from wiring. look at the back of it and you will see the bulbs, remove them by twisting anti clockwise half a turn. replace in reverse order.
