Lighting Fixture Rust

I had a new liner put in two years ago and I just reopened the pool and I'm seeing what looks like rust seeping out around the edges of the light fixture. Plus, hard to see from the photo, the light seems to be taking on some water. I am on a chlorine system but switching to salt in the next two weeks. I'm thinking if I dont address this now it's going to get worse quick. 


How do I fix this and do I need to drain the pool to do it?

You will need to replace the face rim on this light.  It might be your niche that is rusting.  So that also might need to be swapped out too.  Not sure what light this is, but you might be able to get a plastic rim / niche for this light.  Here is the link to light parts...

Thanks.   Based on the size, I believe that I have a large stainless pentaire niche. I removed the light and the interior looks ok.  I think this rust may be coming from the steel pool backing panel which feels solid at least.  

Do I need to drain the pool down and pull back the liner to install this?  I now I dont to just change the fixture but I'm not so sure about a new gasket and faceplate and cant find a lot of guidance online.  I am wondering if this is a DIY job or something I need a pool pro for.

I made this video years ago replacing the light (gasket and faceplate) on my sister's pool...

I want to say it was a Pentair, but it's been a while since I last did this.
