I installed a set on my wife truck, she love them. she was complaining that she could see to backup. The first night she back in between to trees in dark section at the neighbors no problems. I had a little trouble with one of the scotch loks, I suggest stripping the insulation on the wire a little on the contact sides for a positive electric connection. I like that shackle trick, I will get a pair for the tow chains.
