I just purchased my first KTM 03 450exc. My question is how do you switch between Hi and low beam on the light. Here is what I have: A very bright headlight, To turn on you pull up on a little switch on the right side of the guage pack. There are no other switches besides the fan and the three buttons to operate gauges with left thumb. There is three wires going to the head light so I assume there is high/low. Thanks to any help.
