Asumming this is not for actual night flight any wired lamp is going to have to have wires and your only options are to run them internally to look good or externally and they are not going to look good thats a fact.

One little trick I did on my Champion Lancer is a simple landing light in the nose with a self contained LED lamp with its own battery (three bucks at Walmart) Its accessed from a hole around the the nose wheel. Agine this is not one of my night flyers for that my lighting recommendations are something entirely different.
