Why do the LED lights on my layout flicker? – Reader Q&AOn October 31, 2016 Intermediate No Comments Tags: Q&A
If the lights on your layout flicker, follow this advice that I gave to Paul who contacted me over the weekend. The answer was simple but of
Over the weekend I got an email from a visitor to MRE who was having problems with the LED lights he’d fitted into an engine shed on the layout.
The lights were coming on but flickered.
While an interesting effect it wasn’t the look Paul required and was disconcerting distraction on the Ratio model he’d spent ages making..
After a few emails back and forth the problem became apparent.
He’d connected the LEDs to the 16V AC accessory terminals on his Gaugemaster controller.
The problem, of course, is that LEDs typically need DC — direct current. Hence using the AC terminals was producing the flicker he’d observed. Actually, it’s likely that with prolonged use the AC supply will probably destroy the LEDs!
I suggested he use the DC accessory terminals that are available on the Model D controller being used and this solved his problem. (The AC terminals should be left to point motors, etc)
