Narrative:

During takeoff the flight deck had a problem with instruments blacking out. When the emergency lights went on in the cabin; we were taking off and after about 15 mins the first officer called back and said that the radar system went black and that everything went black in the flight deck. Then he made an announcement to the passenger that we were experiencing a problem with the radar and since we knew there was thunderstorms in the area we were going back to ZZZ and would be on the ground in about 5 mins and that we expected a normal landing. After about more than 20 mins of flying around the captain called back and asked me if the landing gears were down and informed me that they did not have any indicator lights to help them tell if they were down or locked. The captain told me that I should prepare the cabin for an emergency landing and that the fire trucks would be meeting the plane. The captain then informed the passenger on board as to what was going on. I briefed the passenger and demonstrated the brace position to them and informed them that I would tell them as to when to brace. We were about 500 ft from the ground and I had them brace until we were safe on the ground. The passenger were placed on a bus on the tarmac and taken to the terminal. We informed them that we had another plane and would be continuing as soon as we could get the other plane.
