Does anyone know the diameter of the new bars that are used on the S40's. I need to install an electrical switch and am looking at the Pingle Button Switch. The switch is to turn on (when needed) a foward facing Blue Strobe.

Thank you. Thats what I was hoping. I found the switch but it only come is 1" ID.  My only next question is, where would be the best place to pull 12v for powering the strobe? It is a realative low current but i want it to shut down  with the ignition. I have been know to leave the light on in my car after ariving at a scene and I dont think that would be a good idea on the bike.
