I have a 1999 Lariat with signal mirrors standard. I'm not sure if Muth is the OEM for the mirrors on my truck, however after about 6 months both mirrors began to turn black. I went to the dealer and he said it was an extremely common problem and it was fixed under warrantee. In other words see if you can get a warrantee with the mirrors.Because if mine are Muths, and they haven't corrected the problem, yours will turn black also!!

Mine came with a card to fill out and send in that gets you a one year warrantee. I guess it's a good thing I saved the stock mirrors.
