Mapping LED

I search the forum and many other places and did not find the answer. 
I own a ddj-rx and will love to come back to it after my trip to Europe, but as for now, I bought a Traktor X1 and map mostly everything, I just have to get the led light up. Can you direct me in the good direction please, it will help a lot of other djs too...

As I read in your forum, I did open the NI controller editor but what to do with it is unclear too .

Thank you .
