The blue main beam warning light on my 2006 RRS is not working. Does anyone know whether this is a replaceable bulb or whether a whole new instrument cluster is needed?
Any advice appreciated.

It might be worth getting the fault codes read first to find out if there is a problem with a module or wiring - don't just assume it is a failed light.

The lights behind the instrument panel are LEDs on a printed circuit board. If it is a failed light and you can handle a soldering iron perhaps you could find replacements from a Chinese supplier or get hold of a salvage panel to cannibalise and make a repair?

Our friends at Powerful helpfully posted these videos showing how to remove the instrument panel and dismantle it:
