Discovered that some of the bulbs were out on the climate panel. Tiniest bulb sockets I have ever seen. Anyway I bought a dozen grain of wheat bulbs, use a magnifying glass/tweezers and for about $ 4 bucks I replaced them all . Sockets pretty tough to remove bit some jewelers screwdrivers did the trick.

 

These would be the fibre-optic light bulbs? - goes to the temp as you mention as well as the light switch and head light control panel?

If they are the ones - they are very small, good to know they are changable - any chance of advising what part number the bulbs are

Cheers

You can get them on ebay just get 3mm 12v grain of wheat bulbs. There are also colors. I used green.
