Holsen I've got massive interference, but only at low beam! So this could be very interesting knowledge, but to get it right I have a few questions.1: You've changed the small socket screw to a headed bolt and removed the paint underneath the head, to make contact between the "silver" unit containing the LED plus electronics and the heatzink?2: You've attached a wire from the ground connection on the 3 wire from car to bulb and soldered the other end to a screw jammed into the heatzink?
