LED's last for thousands of hours, I wouldn't worry about replacement LED's. I broke one of the GF's mirrors and had been checking these out, glad to hear some possitive comments. In another thread though a guy said they suck?

 

My mirrors came today. I haven't installed them yet but overall the quality looks pretty good. Will connecting them to my other blinkers cause any problems with them functioning properly? (these are LED's and my side blinkers are standard). Thanks!

 

So after a closer look at the mirrors, I realized that the mounting plates and stems were different. One is correct for the f4i, the other is obviously for a different bike. So far the seller has been good about the mix up and asked that I send them back and they will then send me a correctly matched pair. I did ask that they reimburse me for the shipping but we'll see.
