How hard to replace headlight switch on 67 Valiant?

Correction, got a chance to look at it after work today and found the wipers work, the alternator guage, and the flashers work as well. I unscrewed the fuse box to get a better look at it and as far as i could tell the fuses looked fine, nothing broken. I tried to pull the one that was marked "inst. cluster" and it broke the glass.
