That proves that the sets already either have just one diode, or have managed to build reverse blocking diodes into the lamps (the lamp sockets are polarized, btw).. Christmas Light Safety and Storage. Blinking Christmas Light Circuit Diagram. Your adaptor has just one diode and will definitely force the use of half a cycle - you will begin to see a flash after you add more lights, so use a diode bridge instead (and perhaps an input filtering choke too if the current is great). Christmas lights tend to flicker, or there could be some missing or not working along a string, which the camera can pick up as an ungainly black spot … 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 capacitance in the box. Stock up. But even the minimum DC level on the waveform is far from the point where you'd cause the LEDs to go out, or even dim significantly. If you plug several of these light sets together as I have done, be aware that if the plugs are not polarized, subsequent strings will either light or fail to light depending on which way you plug them in. Christmas lights Trying my hand at custom length Christmas lights this year.
