Narrative:
I was acting as pilot in command and the student was performing multi engine flight training. Preflight; taxi and departure were completed normally. On our way back to ZZZ; my student extended the landing gear as normal procedure and we noticed that the right landing gear light was not on green; also the red unsafe light was still on. I proceeded to check it. I replaced the bulbs to make sure the light bulb was not a problem but green light didn't come on. We tried to do some more cycles but same problem happened; still right landing gear was not turning on. After that I followed poh emergency procedure as listed and performed the emergency extension. This was also unsuccessful. After emergency extension was released; I tried to lock it performing yaw; pitch and roll maneuvers; but the green light on the right landing gear was still off. I contacted ZZZ tower and requested for a low visual approach so they could verify the status of the landing gear. ZZZ tower visually checked it and advised that it seemed down for them. After that; I performed a right traffic pattern and flew back to land. When performing landing maneuver; the right landing gear collapsed. I immediately proceeded to secure the airplane shutting off fuel selectors and the mixtures. This situation resulted in a runway excursion to the south side of the runway. When the plane stopped; evacuation was performed normally and no injuries happened to either of us.

Title: PA-44 flight instructor reported a main landing gear extension problem that resulted in a gear collapse on landing.
Narrative: I was acting as pilot in command and the student was performing multi engine flight training. Preflight; taxi and departure were completed normally. On our way back to ZZZ; my student extended the landing gear as normal procedure and we noticed that the right landing gear light was not on green; also the red unsafe light was still on. I proceeded to check it. I replaced the bulbs to make sure the light bulb was not a problem but green light didn't come on. We tried to do some more cycles but same problem happened; still right landing gear was not turning on. After that I followed POH emergency procedure as listed and performed the emergency extension. This was also unsuccessful. After emergency extension was released; I tried to lock it performing yaw; pitch and roll maneuvers; but the green light on the right landing gear was still off. I contacted ZZZ tower and requested for a low visual approach so they could verify the status of the landing gear. ZZZ tower visually checked it and advised that it seemed down for them.
