Narrative:
While flying wbound; I was advised that a helicopter Y was 10 mi southeast of my position; nwbound to the hospital. As helicopter Y came nearer to my position; he reported my aircraft in sight. I was still unable to see helicopter Y and continued wbound. I was advised by tower that he would pass behind me. As helicopter Y came within 1 mi; tower asked helicopter Y if he still had me in sight. Helicopter Y reported me in sight and stated that he would pass behind me. Tower advised him that I was wbound. I still had negative visual contact. Suddenly helicopter Y passed in front of my aircraft causing me to perform a quick stop in order to avoid his aircraft. My aircraft had white 'tell tail' lights. I believe that the pilot of helicopter Y mistook the 'tell tail' lights for landing lights; thus he passed in front of my aircraft by mistake.
