This unit is specially designed by S3 to easily fit replacing the standard On/Off handle bar Switch.
Fitted in seconds by simply detaching the On/Off switch connector and then plug in the Lanyard, no rewiring involved. Fits directly onto all bikes already fitted with a handlebar on/off switch.
It is now a enforced rule by the ACU that all bikes must have a safety power cut out device fitted and entry to events will not be allowed without one.
