With proper fairing in of the light no matter where they are mounted, be it gear leg , wheel pant, belly of the fuselage, leading edge of the wing. They could be made to follow the flight path of the plane with a microswitch and motor similar to the one used to set and adjust the trim tab's on some of the KR's that are flying. Once set the beam of light would follow the flight path of the plane and auto adjust to flight attitude within the given ability of motor travel used. Which if memory serves, in some was the electric mirror adjusting motor from car's and truck's.
