The light that illuminates the outside temperature readout on my W210 instrument cluster must be going because the brightness is about 1/2 of what it should be. This is the same area of the instrument cluster that shows the word "Service" as part of Service In X Miles if the O button were depressed twice. The word Service is also dim.

After reading other posts on a similar topic on this forum, am I correct that this problem is likely a bulb that has gone bad?

Thanks.
