Somehow my right rear turn signal came loose when I was messin with my bike and I cant figure out how to tighten it back up. There is a nut on the inside of the fender that is tight as can be and the outside piece that the bulb goes into is still very very loose, like hanging on by one thread loose. It looks like the same bolt that runs all the way through that has threads on both sides. but I am stumped and can't ride my bike until I get this fixed! I NEEED HELP PLEASE!!! I am very frustrated and want to get back to riding.
