Signal Dynamics is an electronics manufacturing and mail order company founded in 1990, and located just outside of Jacksonville, Florida. The primary function of the products we offer is to increase the visibility of motorcyclists to other vehicles. When we started we only had one product, the BackOFF Brake Light Signal Module. We have now sold over 100,000 Brake light modules, not to mention the millions of other parts we have manufactured and sold. In February 2010 we celebrated our 20th anniversary, and the many accomplishments made over the last two decades. One accomplishment that we are very proud of is the price of our parts. Sure costs have gone up over the years, but through purchasing larger quantities, bringing processes in-house, and embracing new technology; we have been able to maintain an affordable cost for ourselves that allows us to give you an affordable product! Did we mention ALL of our products are MADE IN THE USA - make American, buy American!
