Narrative:

On preflight the position lights were checked and both position lights were operating normally. On takeoff out of opa locka airport (VFR) tower reports position lights were inoperative. I cycled the navigation lights on and off several times and checked the circuit breaker, which was in. I requested the tower for a visual check of my position lights, if they were operating. Tower responded that position lights were in service. I continued the training flight for myself. On return to opa locka airport, the position lights were inoperative, checked on the post-flight. I believe part or most of the flight was accomplished with inoperative position lights. I think the problem was an electrical fault or wiring with the position lights.
