Flickering LED 12V DC LED
Replaced two AC outdoor lights with two 7W Sunthin 12 V LED bulbs running off a 12 V lead acid RV battery being charged by a 50W Renology solar panel and the 10 amp charge controller that came with it. Wire gauge is never less than 14 AWG and the longest run is about 60 feet so voltage drop shouldn't be a problem. The set up worked great for the first two months but recently the light farthest from the battery started flickering constantly when on. It also makes a hissing noise when you are close to it. The wires run from the controller and then split to go to each of the two lights. Closer one is still working fine. I have also switched bulbs and the fixtures but still having the problem. I'm guessing a loose connection but I was wondering if there were any other ideas as to why the bulb might suddenly start flickering.
