I have just done the same thing, and it is really simple mate. There are 2 screws holding the plastic cover around the dials. Remove them, and then carefully pull the surround out. There is a screw on each side of the dials themselves, remove them and then tilt the dials forward, and pull one side out so as you can see the back of them. In each of the holes, there is a bulb which you can replace. There are 2 types of bulb, both capless (all glass), one big and one small that fit into the individual holders. They are only something like 50p from your local motor factors. Hope that helps Many thanks - I will have a go on Saturday. I did not want to end up with my display in bits and not be able to sort it out.
