We decided to add HID lights to the plane so we bought a light kit from Duckworks that is pretty nice. The lights go into the leading edge of the wing, instead of the tips of the wings. That means that holes had to be cut out of the wing. Scary! Turns out that it wasn't so bad, although the actual installation of the kit was frustrating because the instructions weren't that great. Also, I cracked both of the plexiglass lenses and had to order new ones. Tip - don't clamp down plexiglass. I barely clamped it and it still cracked it. The new lenses were cut and installed and the lights are completely done. Whew, they took way longer than I thought they would but they look nice.
