Narrative:

While on approach to cle the landing gear was lowered. The right main gear did not show down and locked. The gear was cycled several times and we still did not receive a green light. We went through the communication procedures and changed the bulbs but it did not help. We diverted to dtw and our company dispatcher declared an emergency. Cle only had 1 runway open which was 6000 ft with poor braking and snow on the runway. When we arrived at dtw we lowered the gear again. After 20 seconds, we got a good indication that the right main gear was down and locked. We then made a normal approach and landing. We were flying in IFR conditions and picking up light rime ice. We were talking to approach, dispatch, maintenance control, executing the abnormal gear checklist, briefing the flight attendants and flying the airplane. The cle-dtw distance is very short and we were very busy. To our knowledge we complied with all far's and ATC instructions.
