My brand new 1995 S320 had this dashboard lights issue probably within 5 years after I brought it home. I've refused to have it serviced and rather
suffered 
from the partially lighted dashboard, for fear that the perfectly quiet car would get rattle noises after they fix it. This fear was worsen with the fact that I had no clues as what the procedure is to replace dashboard lights.
Thanks to instructions by Chris, my ignorance is cleared now.
The question I'm looking for is "could I follow Chris' procedure for my 1995 S320?"
