The owner's manual states what is acceptable. Drips of water are not acceptable if the vehicle is still under warranty it should be covered if, it is not it won't be. If the vehicle is still under manufacturers warranty the dealer should cover it if not call Ford. I was 3 months out of the manufactures warranty and had an extended warranty and it was still not covered. Fortunately for me, the dealer recognizes that this is a problem and decided to cover half the replacement cost of the light and will install the replacement free of cost whenever I'm ready to deal with it. I wouldn't be surprised if this problem results in a class action lawsuit because, in my opinion, this is a design problem that will eventually affect a lot of the Edges over time. Only time will tell.
