Anyone know how to change/ repair the lighted ring around the keyhole?

I know from when i had the dash trim out working on my radio there is a conventional bulb clearly visable.

Just pop the key hole trim and the two fastners above the cluster and pull the trim off and see what you can figure out. Seems like it just is a wedge base bulb from what i remember. may be a nice place for a colored LED if it would fit
