thanks so much for posting this. i installed KWs a while back and my headlights were point way too high and blinding people whenever i am on two way streets. there tons of people who were flashing me because my headlights were blinding them. i finally checked my rear light sensor and it was indeed installed the wrong way. i corrected it and now my headlights are perfect!
thanks so much!
