Can affect the temp gauge as well IIRC. Nothing to do with the dash lights though.

Only lights on the SI board are the sevice LEDs and the three small lamps for oil service, the clock symbol and inspection.

The obvious amswer is the two bulbs are blown.
Power for the cluster lights goes in on pin 23 of the white connector (grey/red), and the earth connection comes out on pin 24 (brown/white).
This brown/white wire is earthed through the rotary brightness control in the lighting switch.
