These are needed to protect the low inverse voltage of the LEDs as long as one led is conducting, the other in the antiparallel configuration will be spared.

Also a resistor with a value of at least 1 meg and a voltage rating of 250 to 350 volts(dependent on line voltage) should be placed across the ac line to discharge the capacitor in this circuit when power is removed.

But I gotta tell ya, this circuit kinda creeps me out.  I wouldn't even breadboard this without an isolation transformer, and I bet without one, it'd cause 120hz buzz in any audio circuits placed nearby.

Wow learn something new every day.   It does look creepy the way it was drawn so I will not be trying it any time soon because I cannot see clearly how it works.

They flicker by themselves, you basically just hook em up like a regular LED. Very cool effect to embed them into other stuff.

Since these were orignally using batteries, have you thought about wireing up some batteries?
AA batteries have about 10x to 40x the capacity of the coin/button cells that these lights usall come with.

Yeah, actually, I had originally considered that, but I wanted them to come on only when the light was on. Otherwise, i'd have to have a second switch somewhere, which wouldn't be tough, but. Well, I guess I'm just being picky  :)

Plus I already have one of those "touch sensor" dimmer gizmo's (i'd bought for my arcade cab but didn't/couldn't use it) so I thought I'd wire that in to make it a touch lamp too.
