I went to make a right turn and when I pushed the leaver down it broke in half just before the high beam activation swich. The leaver is made of pot metal and now hangs by two wires. Since my Mark III is less than a year old, one assumes it should be replaced by Hillbank who was my dealer. I am waiting a response from Lance regarding this. Is this a common problem or am I only one who has had this failure? If I have to replace it, does anyone have the instructions for the job?
