Narrative:
Performed maintenance to nosewheel light. Closed nose gear doors after maintenance. Aircraft made air return because of vibration. Suspect 1 or both gear doors became unlatched in-flight. Since this has happened many times before and will happen again, suggest making 'nose door secured' a required inspection item.
