Hi Howard,
As an electronician I would guess it could be a capacitive effect in the lights switch, or either an "antenna" created by the wires to the leds.
The way to discriminate which would be to disconnect the wires from the switch and see if it changes the flickering. If so its the capacitive effect, if not it's the antenna one. Anyway that's just by curiosity but no cure!
To cure I would suppress it by inserting a capacitor (10 nF ceramic 100V) anywhere between each of the concerned circuits and a (good) ground. Probably best to put one on each of the leds so that the connections of the capapcitor are kept VERY short.
Hope this helps.
