Mate they are great, i love them hey......... when u install them, the crimp plugs that plug into the original plug only work one way..... so if they dont work at first you just switch them around then they will work. (its all in the instructions) if u have any questions give us a PM and ill be happy to help u out. BTW when they are first installed and turned on they will usually look white, not blue..... after you use them a bit (2 or 3 days) then they look more blue.
