Valin,

The USAF studies aside, consider these characteristics of light=20 positions.

1. At night, the entire bottom of the airplane is illuminated and becom= es=20 very visible from any angle. This is a great advantage when near=20= an=20 airport.

2. Wing lights do not light up anything but the runway/taxiway, but the= y=20 can be turned on anytime.

3. Leg lights are only on when the gear is extended.

Perhaps you could imbed super bright LEDs all over the place.
