Instrument Panel light out - which fuse?

[Rick M]

I just bought a 1987 300sdl turbo with 197,000 miles. I've been researching and have joined your site, a well run and active one at that. The car needs a little TLC and a new coat of paint, but otherwise it has good service records and runs well. Question: The instrument panel is dark and I do need to see it at night. I've tried, but not yet figured out which small fuse or metal box fuse controls the instrument panel light. Which one is it? Thanks for the help.
