There already are, very bright LED strobes in use on aircraft. All the
exterior lights on mine were solid state, except for the landing light.
There are LEDs that could have replaced that, but I never saw any that had
been approved.
I don't know at how low a temperature they will still function, but I
flew in temperatures a lot colder than most towers would see.
We are using LED obstruction lights in Europe
