Hey Sluggo,
I simply cut a hole in the leading edge, installed pieces of light ply inside the wing, drilled a thru hole, and glued the LED in place. See photos below. Sorry I missed you at TG.
Note: The lights come with a wire lead which is about 36" long. At the mid-point in the wires, there is a piece of heat shrink around a small circuit-card board. If you want to shorten the wires, that is OK, but make sure you still install the board as it has a surface mount resistor installed.
Regards,
Jim
