I had these mirrors on my car for less than a year. I find them to be very cheap. This past winter I went to a touchless car wash, (how ironic) and when the rinsing pass came it was close to the car, it broke my mirror off. To make a long story short they did pay for the mirror and I put the stock ones back on. Not only that, the led turn signals were only held in by silicone, over time they both just fell out. Anyways when they were on I wired up the signals to the front turn signal under the hood. I couldn't find the signal wires anywhere else but there. I never did hook up the power wires, I just adjusted the mirrors manually. They were the gen 2 style mirrors.
