Affix a mirror to your bike helmet

I figured out where the mirror needed to be to be useful and marked the wire location on the helmet with pencil. I took 2 packs of Sugru and worked it around the mirror mount (made for sunglasses and pressed it onto the helmet. I made sure it made good contact with the helmet and smoothed it out. I have ridden about 200 miles with it so far and it is working perfectly!
