2 set of wires for main cabin light?!

Hi everyone, I removed my main fixture in the cabin to put an LED one instead, and I was surprised to find 2 set of positive/negative wires coming from the hole. For some reason, they had been merged together in a Y shape, to then be connected to the fixture positive and negative terminal. Is there an historical reason for this (e.g., there used to be 2 lights there?). What's the proper way of fixing that? Can I just push back 1 set of positive/negative wires back in the hole, and only reuse the 1 set left? The new fixture I got doesn't have a lot of room for wires, so I need to keep it to minimum. Thanks!

On my boat the lights are daisy chained so one of each wire comes from the source and one of each goes on to the next light, hence two of each coming out of the overhead liner.

It is probably how other light(s) are wired farther down on the same circuit by daisy chaining them together. If you separate them the downstream lights won't work. You could add a short wire to each junction (a pigtail) so you only have to pass one set into your new fixture and push the rest back into the overhead.

I'd not recommend the pigtail Allan suggests. It adds additional connections and sets you up for more circuit problems later. The school solution is to attach both positive and negative wire sets to the light at the light, just like you would do in home construction, but without the wire nuts of course.

Wow that was fast responses. It's definitely a daisy chain setup, I should have thought about it. I'll leave the setup the way it is and try to find a way to push all these wires back in the overhead liner. Thanks!
