So. Been wheeling a ton lately.. Guess I was a little too rough on the ****, but any ideas on how to fix this? Tried twisting the wires and shoving them in, one came off so going to have to reconnect them but this isn't a problem is it?

I did a search for this but not sure on what this thing is called..

Also.. I was looking at a LED post, is there a way to open this up and switch it out with a led? Love for it to light up blue but not sure of how to open the handle + what bulb goes in it.. Figured while its off I might as well.. Thanks!
