I just bought a new 13 850xp and was reading on here about the 3 light mod. I guess I'm missing something that I could not find when reading the treads about this mod. Anyways what exactly does this mod do? I mean does it light up all 3 lights to work on the time on high and low beams? Next question is my 13 on low beams stay on when I flip the switch to high along with the top one coming on, so would this mod even be needed on my machine? Thanks for the help guys loving the new machine.
