Bike tail light problems

So today I got motivated and put the tail light for the virago that has been sitting in a box in my room for several months to use. As you might know, the tail light fixture got broken a while back in a friend's trailer so I glued it back together. Now though the running light doesn't turn on so I can't really ride it at night because no one can see me without any lights from behind.

Break light still works both with broken tail light fixture and replacement. So, I'm not sure what needs to be fixed, something is broken or not connected right :(
