Narrative:
We were cleared to climb and maintain visual with traffic that was at 16000 ft. We were at 15000 ft. The sf-340 flashed his light and we responded by flashing ours and started a slow climb. It appeared that the saab would pass behind us, and it did. The saab pilot announced that his TCASII had said we were too close. He was very upset. We do not have TCASII and it is hard to estimate distances at night visually. This type of situation could be avoided by requiring all air carrier's to have TCASII.
