Do these illuminate when you put your lights on? if not can you buy ones that do?
Thanks

The bulb will have gone. I can't remember what the bulb type is but it's behind the centre knob. Pull the knob towards you and it'll come off. Then use some long nose players and you can get the bulb out. They're dead cheap on the internet.
