1. An aircraft exterior lighting multi-LED array enabling variable beam profiles for both landing and taxi lights upon an aircraft, said exterior lighting multi-LED array comprising:
a fixture;
at least one central emitter disposed centrally in the fixture under at least a first collimator; and
at least one peripheral emitter disposed off-center in the fixture under at least a second collimator;
