Can small planes see lights on the ground?
Yes we can see lights on the ground from small planes, but your extra lights do not help approaching aircraft. If anything they may serve to disorient pilots. In low visibility situations, provided the pilot is properly rated and the aircraft is properly equipped they may be flying IFR. Under these types of operations when popping out of the clouds we may be looking for runway lighting. Other lights on the ground can (and have been) confused for runway lights in the past.
