    Hello everybody. Forgive me if this isn't the proper forum for this question.

    I'm restoring a 1973 B25B, And I'm almost finished. I need to replace the yellow and red indicator lamps for power and standby. I tried to do it myself, but I blew them out, so now it's in a pro's hands:p. He thinks maybe the lamps have polarity, and that's why they blew, but he isn't sure. Do they, and how can you tell +\-? Also, are both lamps fuse protected?

    Any help is appreciated!
