The Aero LED lights for the wing tips are adjustable. The lower portion of the light moves back and forth with screws allowing adjustment from outbd to inbd. The top part of the light pivots on a plastic fixture that is attached to the outer inner wing tip. The fixture must be attached enough to the light to make it functional. I needed to build up the inner surface of the wing tip so the fixture was close enough to the light. I then secured the fixture with a flox epoxy mixture.
