Does anyone know why LED lights flicker? Some of the old bulbs (912's) we placed with LED flicker. But the biggest problem (and most expensive) is that all four of the recessed puck LED lights I installed above the sink flicker a LOT.

Looks like maybe low voltage. Can you pull the light and check the voltage while it's turned on? Get a digital multi meter if you don't already have one, you will get lots of use out of it! Good Luck.

First and foremost, make sure your bulbs will handle ~8-16V.
Cold solder joints on individual leds will cause individual leds or groups of leds to blink. The same thing can cause the entire light to blink. As will a poor socket connection.
Then there are just plain cheap fixtures that are going to work consistently. I know I've bought a few.

So right there, you get what you pay for! That being said, I quite often order LED's from China at around 1/10th the price they are here after all the mark-ups. I figure a 10% failure/junk rate, and still come out much cheaper. I can use that money for other "stuff" Some LED's do flicker, and just have to be replaced.
Because all 4 are flickering, probably voltage problem.

Thanks for the replies. I checked the voltage. All four are getting 13.31 volts. I have called the company and they send me replacements (twice). There has to be a voltage issue.... I just can't figure out what it is. I used the same DC power that was powering the original light (a florescent).

Is that voltage at the lights? While the lights are on? If so, you have me stumped.
Hope someone else can help out.

I had a flickering light issue in my Bounder before I installed LEDs. It seemed to be intermittent until I discovered it only occurred when a particular combination of lights were on. I changed the converter/charger and problem fixed. My $.02.
Just some of the LED's. They blink until they warm up then the blinking ones go out completely. But they start all over again the next time I turn them on. Now there are several LED's in each light fixture that are permanently out.
Our MH has LEDs throughout, both 12V and 120V, both expensive and "direct from China". A couple of months ago lots of them began to flicker to the point that I was considering replacement of lights and dimmers.
To make a long story short, our Progressive Industries power management system began to trip out claiming that there was "high voltage" on one of the two 50A lines. I called the power company out to check and they found that the difference in voltage between the two lines was ~3-4V which was indicative of a slightly floating neutral. They tightened all the connections between my pedestal and the distribution transformer and everything was then fine--the voltage difference went back to ~1V and the flickering stopped.
What was no doubt happening was that one or more connections in the circuit had poor connections which were exhibiting very rapid spiking but enough for the Progressive to notice it. Remember that if one side of a 50A circuit has a low voltage, the other will have high voltage, even for just a moment. The same thing can happen inside your coach at the breaker box.
My suggestion is to open your breaker box and tighten all the connections there and everywhere else the wires come in from the pedestal.

As redcolorado mentioned, changing the converter/charger may solve the problem. You may have a lot of AC ripple coming from the converter. Does it do when powered only by house batteries and not on shore power?
