Incident Overview
While on approach, the pilot lowered the landing gear, and the landing gear extended. However, the green landing gear annunciator light, which confirms the gear has extended and locked into position, failed to illuminate. The pilot conducted a visual check and confirmed the left main landing gear was extended, while the passenger confirmed the right main landing gear was extended.
