Narrative:

Immediately after takeoff; we noticed the yellow 'gear door open' light. We cycled the gear on initial climb out and the light remained on after the gear went back down as well as when the gear came back up again. All gear green and red annunciations were normal. No vibration or unusual sounds were detected to confirm that a gear door was open.we performed the 'gear door open light in cruise' procedure and complied with the maximum speed limitation. Then we reviewed the 'gear door open light with left; nose; right gear lights green' procedure in the QRH. This procedure calls for a possibility of landing and staying on the runway should the gear doors have to be extended manually. Dispatch told us he would coordinate that issue with maintenance at our destination. Finally; we informed the passengers of the problem and briefed the flight attendants via interphone.we coordinated with approach and station maintenance as to which runway they wished us to land on as we would disable the runway for awhile and asked for the equipment to standby. We put the gear down early and the door light did not extinguish; so we accomplished the QRH procedure mentioned above. [We] landed with the gear doors open and emergency gear handle extended and stopped on the runway to be evaluated. They found no defects to the aircraft other than the doors being down. Maintenance secured the gear doors with the pins from the cockpit and we proceeded to our gate.
