Adding roof lights on xuv825i

I was wondering how to go about adding the 3 sets of roof lights (2sets up front and 1set in the back) when I have the windshield wiper as well?
Each set of lights has a switch and my wiper has a switch, but the jd overhead switch bank only has 3 spots. I was hoping to keep the over head light switches on the overhead switch box? Thanks for any feedback.
