This can be due to many possible factors, including a bad voltage regulator, an alternator that's not in good condition (possible bad diode, bad rotor/stator, poor internal connections), poor/high resistant charging system connections, poor/high resistant grounds, and also the idle surging is enough to cycle the alternator in/out of the charging. LED flickering can be tied back to the driver component within the lamp. Large electrical appliances draw more electrical current when they are first turned on, causing a significant voltage drop, which causes the lights to flicker/dim. The pinball center 'noflix plus' don't show the flickering anywhere near as badly, but they are pricey. I believe he assembled your aircraft when they were delivered a few years back. Particularly when it comes to choice, availability, quality and price. I checked the grounds that were easy to get to, cleaned them and it did not fix the problem. Has anybody else had any issues with their interior dome lights flickering? I've had a few days now that I've noticed when I open my door that that back dome light (possibly the front dome light as well, but by the time I noticed the flickering, all the lights were working) would flicker on and off, and every now and then would just stay off for a few seconds, come on, then go off again. I used all blue LED's and really like how it looks now. The dimming range may be only down to 50% of the light output or the light may dim but start to flicker at some output level. Though an LED lamp or lighting system may be rated for dimming, some dim better than others. Measured light output is the quantifiable value of light measured by a light meter or similar device. Set transformer to ON so lights are ON all the time, then plug power pack into cheap wall timer.
