Usually the lights on the sunvisors are tied in with the dome lights for the fuse. Does your dome light come on? Also depending on the model there is a little cover for the mirror and if it isn't pulled the whole way open the lights will not come on. Some models however should come on as soon as you pull the sunvisor down. If the bulbs are good and the dome light works and you tried everything else I would recommend pulling the visors and making sure that the wires are plugged in and make sure they aren't messed up or anything. Please keep me posted and I will try to help in any way I possibly can. If this doesn't work please post a picture so I can see what you are seeing.
