Changing Bulbs In Dials

[Midsomer B]

Hi, I am a Newbie. I have just bought a C8, having had a very old BX.

I noticed that the dials on the outside of the speedo don't illuminate. I guess it's just a bulb, as I can't find a Haynes manual, how do you replace dead bulbs??

Thanks in advance.

its not really a diy job as they are LED,s soldered into the circuit board
