So has anyone in the USA investigated options to add lighting to a
sailplane?

The new generation of super bright LEDs seem to be a perfect solution
for us. They could even be embedded in various parts of the wingtip or
winglet. A couple AA batteries installed at each light location would
probably last 20 or more hours, so no need to run wires. But since
current draw would be quite low, a fairly lightweight wire would be
suitable.
