there are two little tiny bulbs inside the compass, you have to use a small flat tip screw driver to get them out, you can order there from dealer for cheap if you get a smart parts guy that knows how to find just the right bulb. it fits into a plastic socket that you unscrew a quarter turn to get them out. covered with a blue plastic jacket. I have the part number at home, but I am in Iraq at the moment.
