There is what looks like a disconnect before the meter for the outside lights, but it looks like it missing a switch? How are the lights running and how would we disconnect them for service?
That looks like where a main breaker goes, and the stuff in there looks like the damaged guts of a main breaker. I supremely doubt this is for the outside lights.
This an extreme hazard being just like it is. I strongly recommend you get an electrician out to fix it before it burns someone's hand. What's more, it appears that something that is supposed to be breaker-protected, isn't. So the protection is gone, opening the possibility of a fire.
