while this review is for the front . I have also purchased the rear. i bought my first set about 3 yrs ago. I have had to replace the rear 3 times but this is the first time I have had to replace 1 of the front. I really like the way they look and the finish they give my bike over the stock signals. For what they cost I would expect them to last longer. That being said --- I clock an average of 10k miles a year on my 2011 FXS Blackline.
