Narrative:

During the 'before landing' checklist the right gear indicated unsafe on both primary and secondary indicators. We asked the tower to observe right gear position on our low approach/missed approach and they indicated it appeared down. I asked for a downwind to 36L for another low approach; during which time; we recycled the gear and attempted to troubleshoot our malfunction. The unsafe indicators remained along with the gear warning horn when flaps were extended to 35 degrees. The tower once again confirmed their previous observation that the gear appeared down. I declared an emergency and requested equipment to standby; contacted maintenance and dispatch and completed our QRH checklists; secured the cabin and briefed our plan should the gear fail during initial touchdown and/or rollout. The landing was uneventful and we had maintenance pin the gear and tow us into our gate.

Title: DC10 Captain went around for an unsafe gear indication on both primary and secondary indicators. Cycling the landing gear produced the same result. An emergency was declared followed by a normal landing.
