Several years ago I installed a set of hyperlites on a 1992 R100R. Some while back, I noticed that one side had quit working. When I called the company to see if I could buy only one side, the gentleman told me that he believed that a product should work longer than that.
He said that I shouldn't buy anything, and that he would ship out the necessary parts. A few days later I received a Hyperlite module with connectors.
I just think service like this shouldn't go unnoticed. Hats off to Hyprlite. BTW, I have no interest in Hyperlites; just a very satisfied customer.
