Ok I have reviewed several post from the past. I am sorry if this is a repeat. I am having a problem with my brake light flashing only on at Interstate speeds. If I am riding on two lane roads at 55-60mph it does not do it. I have let the adjustment screw out and I have ran it all the way back in and at each way it still causes the light to flash. I am planning on going on a ride tomorrow and I am planning on just unhooking the switch at the handle and see if that remedies the problem. If it does not does anyone have any ideas on how to tighten the handle to where there is less play?
