Narrative:

Gear indicated down at the beginning of the approach. When 2 mi out, left gear down light went off. Climbed to 2000 ft MSL to check out problem. Recycled gear with no change in the indicator. Followed alternate gear lowering procedure with no change in the lights. Made 2 low passes to see if gear was down. On first pass, we were told that there were 2 gear extended. On the next pass, all 3 were seen. An uneventful landing followed.
