We are excited to announce the immediate availability of our new Street Lite Switch Line.  This lightweight, low cost line of switches solves the space problem when adding accessories on sport bikes.  The Street Lite Switch housings are constructed of durable ABS plastic for dramatic weight savings over typical aluminum products.  The most common uses are for air shifters and nitrous oxide applications, but can be used for any electric device that needs a switch.  The MPS Street Lite Tether Kill Switch addresses safety concerns when racing at sanctioned events.
