Narrative:
While on a CFI training flight with my instructor; I noticed that the display on the radios was pulsing; (bright; dim; bright; dim). The amp meter was not showing a discharge. We started the loss of electrical power checklist; which didn't help or correct the problem; so we decided to land at ZZZ1 airport and call the mechanic. As we were approaching the airport; we tried to lower the gear; but it didn't extend; so we departed the airport pattern to troubleshoot and decided to go back to our departure airport. On the way back we went through the emergency gear extension checklist but were unable to get a green light indicating the gear was down. As is the flight school policy; the instructor would do the landing. At 10 miles from the airport; we called the tower on a handheld radio; declared an emergency and requested that the tower visually check that our gear was down. On downwind for the runway; the tower said that the gear appeared down. We landed with no problems and taxied to the ramp. This was a great learning experience. We used CRM to divide the tasks (checklists; pumping the gear; talking on the handheld radio; etc.); and we both remained calm and professional.
