Just if you some of you don't know, if you have an alienware you can turn on the lights by checking Alienware FX in the more options section in league. If this doesn't work for you (like it was for me) You do these easy steps.

1) Find your league of legends folder
2) Go into your config folder
Default for this is C:\Riot Games\League of Legends\Config
3) open the "game" in notepad
4) find EnableLightFx=0 and change it to 1.

and that's it!
