Narrative:

On the ground in cmh, during the before start checklist, it was noticed that the 'a' gear indication system lights were not illuminated. The 'a' system circuit breaker had popped. It was reset, the captain checked the gear indicator lights, they worked properly. A short time later the 'a' landing gear system circuit breaker popped again. The captain did a walkaround, and we discussed the wet sand on the gear area. He continued to work on the situation while I did the load manifest and got the clearance. We taxied to runway 28R and took off. I was the PF, the captain was the PNF. Upon gear retraction the gear indicator did not show a positive up indication. The gear was cycled up then down again, the same thing happened. During the cycling of the gear the 'a' gear indicator did not show a positive green indication. I stated my concern to the captain and suggested that we return to cmh. He noted that, but elected to continue on and troubleshoot the problem. He notified ATC of the problem. He contacted maintenance and ran the appropriate checklists. He contacted exceptions and briefed the flight attendants and the passenger. I flew the aircraft and monitored communication #1. As a precaution, the crash fire rescue equipment trucks were rolled and we landed without incident and taxied to the gate.
