Hi there.I was about to change a ceiling light for my daughter flat,to a drop down so she can put a lampshade on.The fitting is quite old and the wiring I found can be seen in the photos.There are 3 reds twisted together,then 3 blacks,of which 2 are in 1 connection and the other in another connection point.Could someone please describe to me how they would go into a modern light fitting.Many thanks
