Narrative: I departed around XA:30 and was set to arrive at ZZZ1 at XC:35. Upon my descent into ZZZ1 I began experiencing loss in power and noticed my low voltage light turned on. I tried turning the pilot-controlled lighting at ZZZ1 on; but my radio was not transmitting a signal. To make sure it was not just a problem with the lights at ZZZ1; I flew over to ZZZ2 and also could not get the lights to turn on there. With my landing light being inoperable because of power loss; landing at a dark airport was not a safe option. At this point a tried making a call but had no luck transmitting and [advise] by squawking 7600. I started flying to ZZZ3 to see if the airport was illuminated but when I arrived it was dark.At this point I only had 30 minutes of fuel remaining and concluded I needed to start flying towards ZZZ immediately to ensure the safety of myself and my passenger. I flew towards ZZZ at 2;000 feet; stayed clear of Class B airspace for as long as possible; and was closely watching for traffic visually and on my iPad with the ADS-B in device I had connected. After flying above ZZZ4 and seeing the airport was dark I continued flying to ZZZ and concluded that it was my only option to land safely. Since I was low on fuel; when the airport was in sight; I began my descent into Runway XXR. During my approach I saw another aircraft taking off Runway XYL; I immediately turned left and landed on the parallel Runway XXL to stay clear of departing traffic. I taxied off the runway as fast as possible and worked with airport operations to safely secure my Cessna.This experience has taught me a lot of things to prevent [a situation] like this from happening in the future. I have purchased a handheld radio to have as a backup at all times when flying in the future and am actively talking and learning with my mechanic to better understand the electrical systems in my aircraft. I will always fly with a backup radio in the future especially at night to have the ability to turn on lights at uncontrolled fields and have an extra line of communication if necessary.




Synopsis: C150 pilot flying in the middle of the night had an Electrical Power failure and could not activate airport lighting. When the pilot flew to the nearest commercial airport which was open with lighting and approached to land they had to sidestep to a parallel runway due to an opposite direction departure.
