Pool and Outside lights problem

[panuts]

I have a problem and tried to seek help. No answers though, so I thought I would ask here in my favorite site.
I am having a problem when I make a pool and place the pool lights in it and toggle to night they do not light up. I have tried placing outside lights on the lot and I only get one light that lights the rest of them look purple. Can someone please help I am not sure how I can solve this.

You can change the color of some, (if not all), of the outside lights. Click on one of them and make sure the color is set to white.
