Narrative:

Added power for takeoff and left reverser unlock light illuminated. Retarded throttles, taxied off runway and cycled reverser on taxiway. All indications were normal so I taxied back and took off. Uneventful flight. My judgement was that the reverser was not seated after a previous landing.
