Flickering instrument panel lights

Just bought a used 2013 GS, and noticed the blue instrument lights on the left side of the tach flicker on and off occasionally; probably bad bulbs or a loose connection. I also seem to have a bulb out on the left side of the temp gauge. All the white lighting when in GS mode works fine, so I assume there are two different bulbs used for the different colors (as opposed to multi colored LED lighting).

Anyone ever do any dash lighting work or experience this issue? Wondering how difficult it is to get the gauge cluster out to fix these, and what bulbs are needed.
