It looks like the bulb broke free from its threaded base. You should be able to disconnect the power and unscrew the base from the socket. Might need a pair of needle nose pliers to get a grip on it.
There should be some identifying marks on the underside of the bulb (the sort of gray bit). You might have better luck taking them to a batteries and bulbs store or even a local home improvement store
Kill the power to the socket and unscrew the threaded base. Pliers may work, I think there's a tool for this too. I've also seen a potato used but that requires the bulb to be broken off. I don't know if you'd get enough grip without the broken glass
I was going to just unplug the cables at the top of the unit, but since they won't come out, a full power cut is the move. Haha. Thank you for the safety advice!
I'm also going to wait until my friend is here juuuust in case.
