As for having the flicker come back after adding more lights, it is most certainly true (capacitors have a finite capacity), but you have said the lights keep glowing after you switch off the display, this indicates you are using a massive capacitor and this issue will not appear unless you connect much more, and once it does you can use a full wave rectifier to keep it at bay without needing to increase the … Purchase extra LED bulbs, if you do not have any, at your local store. But, in reality, it is a spirit sign; something you never thought a flickering light could mean. So in that case the flickers would be 2X as fast, but the on/off duty cycle would still likely be well over 80% (on to off ratio). To stop the flickering, add a power conditioner to the line supplying the power to the LED. Light bulbs that aren’t fully secured in their sockets are receiving inconsistent power, which results in inconsistent lighting. Their shine is brilliant as they distribute light more evenly than traditional lights. In this circuit you’ll only need 4 components + the LEDs and the resistor.
